All you need to do is find the surface area of the pyramid.
To do this we take the four triangles on the top.
For one triangle, 356*440/2=height*base/2
That gives us 78320 ft^2 for one triangular face.
Since there are four of them, 78320*4= 313280.
All you need to do now is add the dimensions for the base.
It's a square with one side 440, so really its area is 193600.
Adding this together we get 313280+193600=506880.
The answer is 506880 square feet of sheet metal.
If it's an exact copy one would expect it to just collapse because aluminum isn't that strong, especially when the size of a great pyramid.
Also can you tell me what this was for because I may have misinterpreted something.
Maybe a shop class?
If that were the case you would need to scale it down.
