    Step-by-step explanation:

    This only works if the room is a prism shaped, or cylinder.

    Volume of a prism or cylinder is area of he base times height. So since we know the height and volume we can fand the area.

    V = h*B

    B = V/h

    B = 400/25

    B = 8

    This is a very narrow room, anyway, the area of the base, which we want to carpet is 8 square meters. Can you figure out how much it will cost since each square meter will cost 5?
