The base of a prism is a rectangle. The length of the rectangle is 4 7/8
inches, and the width of the rectangle is 5 inches. The height of the prism is 12 1/2
inches. Which calculation gives the volume of the prism?
A. 4 7/8 + 5 + 12 1/2
B. 4 7/8 times 5 times 12 1/2
C. (2 times 4 7/8) + (2 times 5) + (2 times 12 1/2)
D. (2 times 4 7/8 times 5) + ( 2 times 5 times 12 1/2) + (2 times 4 7/8 times 12 1/2)
B. 4 7/8 times 5 times 12 1/2
To find the volume of a prism, you multiply the area of the base by the height. In this case, the base is a rectangle with length 4 7/8 inches and width 5 inches, so the area of the base is (4 7/8) x 5. Then you multiply this area by the height of the prism, which is 12 1/2 inches.
Therefore, the correct calculation is: 4 7/8 x 5 x 12 1/2 = 241.875 cubic inches
