Question

rectangular pyramid has a length of 7 cm and a width of 9 cm. Its volume is 231 cubic centimeters. Use the formula for the volume of a pyramid to calculate the height of this pyramid


















------------------

Answer 1

Volume formula: V = (1/3)·(base area)·h, with base area = length·width = 7·9 = 63 cm².

So 231 = (1/3)·63·h → 231 = 21·h → h = 231/21 = 11 cm.

Height = 11 cm.
