The base area is 14 in ² 
The volume is 30.8 in ³ 
For a prism of any cross-sectional area,
Volume = base area * height
=>
30.8 = 14 * height
Solve for height
Height = 30.8/14 = 2.2 inches.

Ans. Joseph has to make the box 2.2 inches high.

19.  Hexagonal prism
Given 
Cross section area = 17.01 m ² 
Height = 16.2 m

Using above formula for volume,
Volume = 17.01 m ² * 16.2 m
=275.562 m ³ 

Answer: The volume of stone is 275. 56 m ³ approximately.
