How do you find the surface area of a pyramid?

To find the surface area, use this pyramid surface area formula:

Surface Area = ( .5 x Base Perimeter x S ) + Base Area

S = Slant length of one of the triangular faces

Example: The surface area of a regular triangular pyramid with base area

of 32 square inches, base perimeter 24 inches and slant length of

8 inches:

Surface Area = ( .5 x 24 x 8) + 32

Calculated out this gives a surface area of 128 Square
Inches.
