Step-by-step explanation:
surface area if pyramid=area of base+combined area of lateral faces.
area of base=8×8=64
combined area if lateral faces=area of one triangle:area=base×height
=8×12=96
Total surface area=64+96
=160m square
Answer:
SA = 254
Equation for a Pyramid (Surface Area) is : 2bs + b^2
2(8)(12) + [tex]8^{2}[/tex] =
16 (12) = 192 and 8^2 = 62
192 + 62 = 254
I hope I helped ;)
