The base of a prisim 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 prisim is 12 1/2 inches. whitch calculation gives the volume of the prisim
A 4 7/8+5+12 1/2
B 4 7/8x 5x12 1/2
C (2x4 7/8) + (2x5) + (2x 12 1/2)
D (2x4 7/8) + (2x5x12 1/2)+ (2x4 7/8x 12 1/4)
B 4 7/8 x 5 x 12 1/2
To calculate the volume of a prism, you multiply the area of the base by the height. Since the base is a rectangle, you multiply the length by the width to get the area of the base. Finally, multiply the area of the base by the height to get the volume.
(4 7/8) x (5) x (12 1/2) = 24 7/8 x 12 1/2 = 311 7/8 cubic inches
Therefore, option B is the correct calculation for the volume of the prism.
