    let us take first, the bottom part of the building which is .ahemm is a rectangular prism |dw:1437696377087:dw| now, notice the bottom part is not going to be painted, because, is touching the ground and the only way to paint that part is by ...hmm dunno calling godzilla and tell him to lift the building for you while you're painting the bottom, so that's no painted the top is not, because, well, the rest of the city hall building is a "rectangular pyramid" and is sitting on top of that, so, you'd paint the prism but first off, let us do the other parts

    I get that the bottom part of the figure (the rectangles) that can be painted are 4 rectangles, each 15x36 feet

    yeap 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

    1/2 * 15 * 12=90 per triangle, times 4 so 360 square feet for the triangles, then the 2160 for the rectangles so 2520 square feet.

    which means city hall needs to buy 10 gallons of paint to cover the monument, bbecause 2520/261=9.65517....., rounded to the next gallon= 10
