Using the information above, we have four triangles so we will use the formula 1/2*b*h which is 356*440*0.5=78320 square feet. Since we have 4 sides and assuming the dimensions are the same we take 78320*4= 313280 square feet for the sides. Now for the base it indicates 440 and for that we know it is 440^2= 193600 plus the original 313280 we get 506880 square feet. Which means we need 506880 square feet of aluminum sheets to represent all sides and the base
Since we are only covering the outside of the pyramid the 280 is irrelavent to this question as well as using the 418 and pythagorem theory I know that each triangle is the same and that the pyramid has a square base.
