Tetrahedral pyramid

What is the surface of a regular tetrahedral (four-sided) pyramid if the base edge a=16 and height v=16?

Correct answer:

S =  828.4

Step-by-step explanation:

a=16 v=16  w1=v2+(2a)2=162+(216)2=8 517.8885  S1=a2=162=256  S2=2a w1=216 17.8885=64 5143.1084  S=S1+4 S2=256+4 143.1084=828.4
