Measures 3162

What is the surface of a regular pyramid with a square base? If each edge of the base measures 40 mm, the pyramid's height is 44 mm, and the pyramid's height is 38 mm.

Correct answer:

S =  5035.3457 mm2

Step-by-step explanation:

a=40 s=44 h=38 S1=a2=402=1600 h2=h2+(a/2)2=382+(40/2)2=2 46142.9418 s2=h2+(2 a/2)2=382+(2 40/2)2=2 56147.3709 S2=a h2/2=40 42.9418/2=40 461858.8364 S=S1+4 S2=1600+4 858.8364=5035.3457 mm2
