Question

10. what is the volume of the prism to the nearest whole unit?

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

Answer:

10. Option 1

11. Option 3

Step-by-step 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

$Volume=lwh=12\times 8\times 4=384\thinspace in^3$

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

$V=\frac{1}{2}bhH=\frac{1}{2}\times 12\times 2\times 18=216ft^3$

Option 3 is correct.
