Question

Find the length of the base of a square pyramid if the volume is 48 cubic inches and has a height of 9 inches. Use 3.14 for pi, and round your answer to the nearest hundredth. A. 4 inches B. 8 inches C. 16 inches D. 24 inches

Answer 1

The volume of a pyramid is equal to 1/3 multiplied by the base of the pyramid multiplied again by the height. In this case, the base of the pyramid is a square. Hence the area should be s^2. The volume now becomes V = 1/3 * s^2 * h = 1/3 * s^2 * 9 = 48. length,s is not equal to 4. Answer is A. 4 inches.
