Square Pyramid
Hence , the surface area of the square pyramid is 340 square feet
Step-by-step explanation:
The square pyramid has a square base
Given that the base side is 10 ft and the slant height of the pyramid is 12 ft.
The surface area of a square pyramid is SA, then
SA = Area of the base + [tex]\frac{1}{2}[/tex] × P × Sh
where P is the perimeter of the base and Sh is the slant height of the pyramid
P = 4 × 10
SA = [tex]10^{2} + \frac{1}{2}[/tex]× 40 × 12
SA = 100 + 240
SA= 340 square feet
Hence , the surface area of the square pyramid is 340 square feet
