Triangular Pyramid Surface Area Calculator
Find the surface area of a pyramid with a triangular base with this Pyramid Surface Area Calculator.
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.
