How to calculate volume of a rectangular prism
Calculating the volume of a rectangular prism is a simple process that involves multiplying the length, width, and height.
Calculating the volume of a rectangular prism is a straightforward process. A rectangular prism is a three-dimensional shape that has a length, width, and height. To find its volume, you simply multiply the length by the width by the height. The formula for calculating the volume of a rectangular prism is:
Volume = length x width x height
For example, if a rectangular prism has a length of 5 cm, a width of 4 cm, and a height of 3 cm, its volume would be:
Volume = 5 cm x 4 cm x 3 cm
Volume = 60 cubic centimeters (cm³)
It's important to ensure that all measurements are in the same unit before calculating the volume. For instance, if the length is in meters and the width and height are in centimeters, you would need to convert the length to centimeters to ensure that all measurements are in the same unit before calculating the volume.
In conclusion, calculating the volume of a rectangular prism is a simple process that involves multiplying the length, width, and height. This formula can be used for any rectangular prism regardless of its size or shape.

In a library, the ratio of maths books to science books is 3 : 2 and the ratio of science books to history books is 1 : 3. If the total number of books is 220, how many maths books are there?
Answer:
60 maths books
Step-by-step explanation:
Let the following be:
Maths books = mScience books = sHistory books = hAnd we have ratios and sum:
m/s = 3/2s/h = 1/3m+s+h = 220From the ratios we get:
m = 3s/2h= 3sConsidering the above in the sum of books:

Find area of trapezium with height 8cm and the sum of its parallel sides as 15cm
Answer:
The Area of the trapezium is \(60cm^2\)
Step-by-step explanation:
Given,
Height (h)= 8cm
Sum of the parallel sides (a+b)= 15cm
Area of trapezium = \(1/2*h*(a+b)\)
=\(1/2*8*15\)
=\(4*15\)
Area of trapezium=60cm^2
Answer: Area = 60 cm²
Step-by-step explanation:
To find the area of a trapezium we use the formula
Area of trapezium = 1/2 (sum of parallel sides) × height
∴ Area = 1/2 ×15 cm × 8 cm
= 60 cm²

how would the expression x^3-8 be rewritten using difference of cubes?
A- (x+2)(x^2+2x-4)
B- (x-2)(x^2-2x+4)
C-(x+2)(x^2-2x+4)
D-(x-2)(x^2+2x+4)
Answer:
D
Step-by-step explanation:
Difference of cubes is as follows
x^3-y^3=(x-y)(x^2+y^2+xy)
*notice how the sign in the origonal equation is the same for the first part but then flipped for the second*****
8 can be rewritten as 2^3 so we have
x^3-2^3 which means that we can use the template from before
(x-2)(x^2+2^2+2x)
simplify the 2^2 into 4 and put the variables in front to get
(x-2)(x^2+2x+4)
This is the same as D
gillan read 3,135 words in 19 minutes let w represent the number of words read each minute if gillian read the same number of words each minute how many words did she read in 1 minute?
The number of words Gillan can read in 1 minute is, 165
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
Gillan read 3,135 words in 19 minutes
The number of words read each minute = w
Now, it has given,
Total words = 3135
Time taken = 19 minutes
For words per minute,
we need to take ratio of total words and total time taken,
Ratio = Total words/Time taken
= 3135/19
= 165
Hence, the number of words in 1 minute is 165

which expression is equivalent to g^2/3h
The given expression \(g^2/3h\) is equivalent to the option (c) \(8g^2/24h\)as we have multiplied 8 in both numerator and denominator.
The given expression is \(g^2/3h\).
Now, to further simplify the expression, we can multiply both numerator and denominator by 8. This gives us:
\((g^2/3h) * (8/8)\)
Simplifying further, we get:
\((8g^2)/(24h)\)
Therefore, the expression equivalent to \(g^2/3h\) is \((8g^2)/(24h)\).
Thus, the given expression \(g^2/3h\) is equivalent to the option (c) \(8g^2/24h\) as we have multiplied 8 in both numerator and denominator.
The numerator is the top part of a fraction, which represents the number of equal parts being considered. It is the value that is above the fraction bar and represents the quantity being divided into equal parts.

length=30cm
breadth=15cm
Now
Area of figure = 1/2*π*radius^2+ 1/2*π*radius^2+length*breadth

David gets half as many e-mails a day as his wife Nicky does. Together they have a total of 147 e-mails for today. How many e-mails did Nicky receive and how many e-mails did David receive?
Answer: Nicky = 98 emails; David = 49 emails
Step-by-step explanation:
Let the number of emails received by Nicky be denoted by a.
Since we are informed that David gets half as many e-mails a day as his wife Nicky does. This can be written as: a/2
Number of number of emails received by Nicky = a
Number of number of emails received by David = a/2 = 0.5a
Together they have a total of 147 e-mails for today. This will be:
a + 0.5a = 147
1.5a = 147
Divide both side by 1.5
1.5a/1.5 = 147/1.5
a = 98
Nicky got 98 emails
David gets: a/2 = 98/2 = 49 emails.

What is a 30-60-90 triangle?In Mathematics and Geometry, a 30-60-90 triangle is also referred to as a special right-angled triangle and it can be defined as a type of right-angled triangle whose angles are in the ratio 1:2:3 and the side lengths are in the ratio 1:√3:2.
This ultimately implies that, the length of the hypotenuse of a 30-60-90 triangle is double (twice) the length of the shorter leg (adjacent side), and the length of the longer leg (opposite side) of a 30-60-90 triangle is √3 times the length of the shorter leg (adjacent side):
Adjacent side = 5/√3

Answer:
B) $3.56
Step-by-step explanation:
The price of one egg: $1.69
The price of a slice of bacon: $1.49
The price of a glass of orange juice: $1.09
Sara buys 2 eggs, 1 slice of bacon, and 1 glass of orange juice.
(2 eggs x $1.69) + (1 bacon x $1.49) + (1 glass of oj x $1.09) =
($3.38) + ($1.49) + ($1.09) = $5.96
Next, add the total gotten with the sales tax.
Sales tax: $0.48
$5.96 + 0.48 = $6.44
Then, subtract the total from the $10 that she used to pay:
$10 - 6.44 = $3.56
B) $3.56 is your answer.
~
Answer:
3.56
Step-by-step explanation:
because first, you 1.69$ dollars 2 times since your ordering it 2 times which gets you 3.38 $ next you add 1.49$ dollars because that's what a slice of bacon cost, then add1.09 since that's what a cup of orange juice cost. Then add 0.48 cents because that's the sale tax, at the end when you add everything up you get 6.44$ then subtract that from 10.00, then you get your answer!
