Question

how do you find a pyramids surface area with lengths: 18,18,and 41 (i will draw)

Answer 1

take the surface area of each of the faces of the pyramid (the triangles) and the base (the square) and add them all together.
F+F+F+F+B= total surface area of a pyramid.

Answer 2

SA = B + 2bs

Answer 3

or you could do the surface area of one face times 4 and the base to get the sum.

Answer 4

The formula above is for the surface area of a square pyramid.

Answer 5

Where B = Base (face)
b = side of the base (face)
s = slant height
