Question

A rectangular prism has a length of 5 1/8 feet, a width of 7 1/2 feet, and a height of 2 feet. What is the volume of the prism? Enter your answer in the box. ___ft³

Answer 1

Hello!

to find the volume you always have to do length times width times height so all you have to do is do
`5 (1)/(8)` TIMES
`7 (1)/(2)` and your answer should be 
`38 (7)/(16)` then do
`38 (7)/(16)` TIMES 2 and your answer should be
`76 (7)/(8)`

Answer 2

Hey there!

The formula for volume is:
l * w * h

Length = 5 1/8

Width = 7 1/2

Height = 2


First, multiply 5 1/8 and 7 1/2 . . .



5 1/8 = 41/8


7 1/2 = 15/2


41 * 15 = 615


8 * 2 = 16


= 615/16

Simplifying 615/16 . . .


615/16 = 38 7/16



Now, multiply 38 7/16 and 2 . . .



38 7/16 = 615/16


2 = 2/1


615 * 2 = 1230


16 * 1 = 16


= 1230/16

Simplifying 1230/16 . . .



1230/16 = 76 7/8 ←


Your answer:76 7/8 ft³



Hope this helps you,

Have a wonderful day! :)
