Answer 7

A triangular pyramid has 4 triangular surfaces. They are all congruent here and they add up to 408. So what is the surface area of 1 triangle?

Answer 8

A pyramid has 4 sides. As such, If the surface area of the entire pyramid is 408 m^2 then the area of a single face will be 408meters/4sides = 102 m^2

Answer 9

so C is right?
