Question

Determine the surface area of a square pyramid

Answer 1

4 triangles and 1 base
triangle is 1/2bh
base is a square


if sides of base is legnth 'b'
and lateral height of pyramid is 'h'

then
SA=b^2+4(1/2bh)
SA=b^2+2bh
SA=b(b+2h)

Answer 2

SA = s2  +  2 × s × l  Is the formula for the surface area of a square pyramid
