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.
Step 4. Calculate the area of triangular spaces by measuring the base and the vertical height of each triangle. Find the square footage by dividing the base dimension in half, then multiplying the result by the height. For example, if the base is 12 feet and the height is 10 feet, the square footage is 6 x 10 = 60 feet. Add together the square footage values of the square, rectangular and triangular floor areas to find the total square footage of your attic.
