Best ResponseYou've already chosen the best response.1yeap for the triangles in the pyramid above the base is 15, the height is 12 get the area of the triangle, you have 4 of them, add them up then add that up to the 2160 of the bottom and that's hwo much area will be painted

Best ResponseYou've already chosen the best response.01/2 * 15 * 12=90 per triangle, times 4 so 360 square feet for the triangles, then the 2160 for the rectangles so 2520 square feet.
