11. What is volume of the triangular prism to the nearest whole unit?
(Picture below)

Answer 1

To calculate the volume of the rectangular prism and the triangular prism you will multiply the area of the base by the height of the prism.

1. V = BH
V = lwH
12 x 8 x 4
V = 384 cubic inches

2. V = BH
V = 1/2bhH
1/2 x 12 x 2 x 18
V = 216 cubic feet

Answer 2

10. Option 1

11. Option 3

Explanation:

Given the dimensions of rectangular prism. we have to calculate the volume of prism.

Length, l=12 inches

Width, w=8 inches

Height, h=4 inches

`Volume=lwh=12* 8* 4=384\thinspace in^3`

Option 1 is correct.

Given the dimensions of triangular prism. we have to calculate the volume of prism.

Length, H=18 ft

Base, b=12 ft

Height, h=2 ft

`V=(1)/(2)bhH=(1)/(2)* 12* 2* 18=216ft^3`

Option 3 is correct.
