Question

Find the surface area of the pyramid. The side lengths of the base are equal.

Answer 1

Surface area is 177.46

Answer 2

Answer:

A = 177.46

Step-by-step explanation:

$A = lw + l\sqrt{(\frac{w}{2})^{2} + h^{2}} + w \sqrt{(\frac{l}{2})^{2} + h^{2}$

A = 6*6+6root((6/2)^2+11.4^2)+6root((6/2)^2+11.4^2)

A = 177.46
