Amount of aluminium can be calculated by calculating the surface area of the pyramid
1. the Base
Since its a square, the area= 440*440 ft. square = 193600 ft. square
2. the top part
This is area of 4 triangles
=4* area of one triangle
=4 * 0.5 * base* hieght
=4* 0.5* 440* 356
=313280 ft. square
Total aluminium required= 506880 Feet square
