Calculate 73704

A vertical regular 3-sided pyramid is given. The side of the base a = 5cm, and the height is 8 cm. Calculate the volume and area.

Correct answer:

V =  28.8675 cm3
S =  73.6868 cm2

Step-by-step explanation:

a=5 cm h=8 cm  S1=43 a2=43 5210.8253 cm2  V=31 S1 h=31 10.8253 8=28.8675 cm3
h12 = h2+(a/2)2 h1=h2+(a/2)2=82+(5/2)28.3815 cm  S2=2a h1=25 8.381520.9538 cm2  S=3 S2+S1=3 20.9538+10.8253=73.6868 cm2
