#18
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.
