Question

What is the surface area of this shape? ​

Answer 1

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 2

Answer:

SA = 254

Step-by-step explanation:

Equation for a Pyramid (Surface Area) is : 2bs + b^2

2(8)(12) + $8^{2}$ =

16 (12) = 192 and 8^2 = 62

192 + 62 = 254
