We need to work out the area of each side and of the base. Since this is a square based pyramid, we only need to find the area of the base and then the area of one of the sides, and then multiply this by 4.

To find the area of the base, we just need to square the side length since the base is a square: 

Area of Base = 440*440 = 193600 Square Feet

To find the area of one of the sides, we use the formula for calculating the area of a triangle:

Area = (1/2) * base * height where height is from the highest point to the lowest. Therefore, the area of one of these sides is (1/2)*440*356 = 313280 Square Feet.

The area of the total surface of the pyramid is one times the base and four times the side:

(1*193600) + (4*313280) = 1446720 Square Feet.

Therefore you will need 1,446,720 Square Feet of the Aluminum sheet to rebuild the pyramid.
