An artist wants to make alabaster pyramids using a block of alabaster with a volume of 576 cubic inches. She plans to make each pyramid with a square base area of 3 square inches and a height of 4 inches. At most, how many pyramids can the artist make from the block of alabaster?

Answer 1

Volume of alabaster= 576 in3
Length for base = 3 inches
Height= 4 inches

Volume of pyramid = lwh/3
= 3x3x4/3
= 12 in3

Number of pyramids that can be made from 576 in3 of alabaster = 576/12
= 48
