The formula used to calculate surface area for the classic square pyramid is: SA = [2 * b * h] + b^2. 1  SA and l represent the same values as before. 2  The abbreviation b represents the base length of the pyramid. 3  Note that [2 * b * h] is used to calculate the lateral area of the square pyramid.
EXAMPLE 1 Finding the Surface Area of a Square Pyramid Find the surface area of the regular pyramid. Draw a net. Area of base Area of a lateral face 5 â 5 = 25 1 â 2 â 5 â 8 = 20 Find the sum of the areas of the base and the lateral faces. S = area of base + areas of lateral faces = 25 + 20 + 20 + 20 + 20 = 105 The surface area is 105 square inches. 1. What is the surface area of a square pyramid with a base side
