How do you find the surface area of a pyramid with a square base?

To find the surface area, use this square pyramid surface area formula:
Square Pyramid Surface Area = 2 x B x S + B2

B = Width of the Square Base

S = Slant length of one of the triangular faces and is calculated from
the height and base width by using the equation:

S= The square root of [(.5B)2 + Height2]

Pyramid Slant, Height and Basesquare pyramid surface area

Example: The surface area of a regular square pyramid with base width
of 6 inches, and height of 8 inches:

S= square root of (9 +64)

S= 8.544

Surface Area = 2 x 6 x 8.544 + 36


Calculated out this gives a surface area of 138.528 Square Inches.
