Question

The volume of a rectangle or prism is 72 m? the prism is 2 cm wide and the 4 cm high what is the length of the prism

Answer 1

9 cm

Explanation:

The formula of a volume of a rectangle prism:

`V=lwh`

l - length

w - width

h - height

We have V = 72 cm³, w = 2 cm and h = 4 cm. Substitute:

`(2)(4)l=72`

`8l=72` divide both sides by 8

`l=9\ cm`
