Question

The figure below is a net for a triangular pyramid.

If all the triangles are equilateral, what is the surface area of
the pyramid, in square centimeters?

Answer 1

339.36 cm^2

Explanation:

14*12.12=169.68

169.68/2=84.84

84.84= the area of one triangle

(84.84)4=339.36

I'm pretty sure, but check my math if it's wrong
