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
