Question

The rectangular solid below has a volume of 5,600 cubic inches, a width of 20 inches, and a height of 8 inches.


What is the length (x) of the rectangular solid?


A 20 inches
B 35 inches
C 200 inches
D 280 inches

Answer 1

Since the volume of a rectangular solid is

\(V = LWH\). then solving for length, you get

\(V = LWH\)

\(\dfrac{V}{WH} = L\), or

\( L = \dfrac{V}{WH} \)

Just plug in your values for V, W, and H, and calculate L.

I knew that

Answer 3

Great. Now you just need to do it.

Answer 4

Simple algebra here. 5600= (20)(8)(x) So multiple the 20 by 8, and you get 160. 5600/160=x=35
