Question

The volume of a rectangular prism is 72 cubic centimeters. The prism is 2 centimeters wide and 4 centimeters high. What is the length of the prism?

Answer 1

The length of prism is 9 centimetres.

Explanation:

Given:

The volume of a rectangular prism is 72 cubic centimeters.

The prism is 2 centimeters wide and 4 centimeters high.

Now, to find the length of prism:

Let the length be
`l`.

Width = 2 centimeters.

Height = 4 centimeters.

Volume = 72 cubic centimeters.

So, putting the formula to get the length of prism:

`Volume = length* width* height`

`72=l* 2* 4`

`72=l* 8`

Dividing both sides by 8 we get:

`9=l`

Length = 9 centimetres.

Therefore, the length of prism is 9 centimetres.
