Answer:

Option B. [tex]21.6\ in[/tex]

Step-by-step explanation:

we know that

The volume of the mold is equal to

[tex]V=Bh[/tex]

where

B is the area of the base of the mold

h is the height of the mold

In this problem we have

[tex]V=324\ in^{3}[/tex]

[tex]B=15\ in^{2}[/tex]

substitute and solve for h

[tex]324=(15)h[/tex]

[tex]h=324/15=21.6\ in[/tex]
