Question

Given a square pyramid with a height of 27 ft and a volume of 5,040 cubic feet, find the length of one side of the square base. Round to the nearest tenth.

Answer 1

v=1/3 times height times base
height=27
base=?
v=5040

5040=(1/3)27 base area
5040=9 times base area
divide both sides by 9
560=base aera
square is side^2 so
560=side^2
sqrt both sides
23.6643=side
tenth
23.7 feet is one isde
