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]
Example: The surface area of a regular square pyramid with base width
S= square root of (9 +64)
Surface Area = 2 x 6 x 8.544 + 36
Calculated out this gives a surface area of 138.528 Square Inches.
