Question

What is the length of a rectangular prism if the volume is 2,830.5 cubic meters, the width is 18.5 meters, and the height is 9 meters?

Answer 1

17 because (18.5)(9)= 166.5 then 2830.5 divided by 166.5 is 17

Answer 2

length = 17 meters

Explanation:

The formula for volume of a rectangular prism is

V = L*W*H where L is length, W is width, and H is height. We are given V, w, and h, so plug those values in and solve for l

2,830.5 = L(18.5)(9)

2,830.5 = 166.5L (simplify the right side 18.5*9 = 166.5 )

2,830.5/166.5 = L (divide both sides by 166.5 to isolate L)

17 = L (simplift the left side)
