Question

You need to fill a clay mold with 324 cubic in of clay. The base of the mold is 15 square inches. How high will the clay be once it is in the mold?

A. 20 in
B. 21.6 in
C.22.9 in
D. 25 in

Answer 1

Option B.
`21.6\ in`

Explanation:

we know that

The volume of the mold is equal to

`V=Bh`

where

B is the area of the base of the mold

h is the height of the mold

In this problem we have

`V=324\ in^(3)`

`B=15\ in^(2)`

substitute and solve for h

`324=(15)h`

`h=324/15=21.6\ in`
