Jamal needs to find the volume of a rectangular prism that has a height of 7 1/3 in a length of 3 1/4 in., and a width of 5 1/6 in. Which option shows the correct method for solving this problem?

Answer 1

The correct method for finding the volume of a rectangular prism is to multiply the height, length, and width together.

So, the correct method is:

Volume = height x length x width
Volume = (7 1/3) in x (3 1/4)in x (5 1/6)in

First, convert all the mixed numbers to improper fractions:

7 1/3 = 22/3
3 1/4 = 13/4
5 1/6 = 31/6

Now, multiply the fractions together:

Volume = (22/3) x (13/4) x (31/6)
Volume = 22 x 13 x 31 / 3 x 4 x 6
Volume = 9002 / 72
Volume = 125.03 cubic inches

Therefore, the volume of the rectangular prism is 125.03 cubic inches.
