Wall height

Calculate the surface and volume of a regular quadrangular pyramid if side a = 6 cm and wall height v = 0.8dm.

Correct answer:

S =  132 cm2
V =  88.9944 cm3

Step-by-step explanation:

a=6 v=0.8 10=8 S1=a2=62=36 S2=a v/2=6 8/2=24 S=S1+4 S2=36+4 24=132 cm2
h=v2(a/2)2=82(6/2)2=557.4162 V=S1 h/3=36 7.4162/3=12 55=88.9944 cm3
