Calculate pyramid

Calculate the volume of the pyramid, whose base edge a = 8 cm and the sidewall makes an angle α = 60° with the square base.

Correct answer:

V =  147.8017 cm3

Step-by-step explanation:

a=8 cm α=60   tan α = h : (a/2)  h=a/2 tan(α)=8/2 tan(60°)=6.9282 cm  S=a2=82=64 cm2  V=31 S h=31 64 6.9282=147.8017 cm3
