Answer:
Step-by-step explanation:
In order to determine the number of 
tiles she will need to cover the pyramid, we would apply the formula for determining the total surface area of a pyramid. It is expressed as 
Total surface area = 1/2 × p × l + base area
Where 
p represents the perimeter of the base
l represents the slant height of the triangular face
Since the base is a square, the perimeter, p is 
12 × 4 = 48 feet
l = 15 feet
Base area = 12² = 144 ft²
Total surface area = (1/2 × 48 × 15) + 144 = 504 ft²
Since the artist decides to cover the metal structure with 1-foot square glass tiles, the number of tiles needed is 
504/1 = 504 tiles
