Regular quadrilateral pyramid

What is the volume of a regular quadrilateral pyramid if the edge of the base is 8 cm long and the height of the side wall is 5 cm?

Correct answer:

V =  64 cm3

Step-by-step explanation:

a=8 cm h2=5 cm  h=h22(a/2)2=52(8/2)2=3 cm  S1=a2=82=64 cm2  V=13 S1 h=13 64 3=64 cm3
