Question

Shawns teacher said that the volume of a rectangle prism is 64 cm³.Shawn said that he has enough information already to find the width. Is this correct? If not,explain why not. otherwise, give the width and explain your thinking.

Answer 1

No

Explanation:

Volume of prism = length × width × height

So,

64 = L × W × H

This is one equation in 3 unknowns

He needs length and height too to find the width

Answer 2

Shawn is not correct.

Explanation:

Since the volume of the prism is given we can find the width as follows:

∵ Volume = length * width * height

∴ Width = Volume/length * height

So he needs the value of both height & length.
