How long must it be?

Question

A trucks cargo area contains 1920 cubic feet of space. If the cargo area is 8 feet wide and 10 feet high, How long must it be?

Answer 1

The volume of a rectangular prism (box) is:

 

Volume = Length * Width * Height

 

We are given:

Volume = 1920 cubic feet

Width = 8 feet

Height = 10 feet

Length = unknown

 

Let's plug these values into the Volume equation above and solve for Length:

 

1920 = Length*8*10

1920 = 80*Length

1920/80 = Length = ?? feet

Answer 2

the answer it's 24feet.

we know the volume V=WxHxL

where

W=8feet

H=10feet

so

1920=8x10xL

1920=80xL

L=1920/80

L=24 feet
