Wat is the surface area of a squre based pyramid???!?!!?

Question

i need it really badly for a school math project and the teacher didnt tell me!!!!

Answer 1

1/2bh is the area of 1 triangle. there are 4 triangles. So 1/2bhx4

1/2x4=2

2bh. 2bh is the surface are of 4 triangles. + the area of the square on the bottom=basexbase

=b²

Total surface area=2bh+b²

b is the base

h is the height of the triangles.

Answer 2

2BH + B^2

B = Base

H= Height
