What is the surface area for square pyramid 15ft , 9.9ft
The surface area of a square pyramid can be calculated using the formula:
Surface area = Base area + (0.5 * Perimeter of base * Slant height)
Given the dimensions of the square pyramid as 15ft for the side length of the base and 9.9ft for the slant height, we can calculate the surface area as follows:
Base area = side length^2 = 15^2 = 225 sq.ft
Perimeter of base = 4 * side length = 4 * 15 = 60 ft
Surface area = 225 + (0.5 * 60 * 9.9)
Surface area = 225 + (0.5 * 594)
Surface area = 225 + 297
Surface area = 522 sq.ft
Therefore, the surface area of the square pyramid is 522 square feet.
