    Since the height is reduced and the surface area is reduced by the square, the side area of the meter is squared, and because the length is 3 times the width, the width is x, and the side area formula is 2 (3x+x).Solve the equation to get x = so the length is 3 * then the volume is cubic meters.

    The reduced surface area is 4 cylinders.

    Get the circumference of the bottom edge.

    The length is 3 times the width, 200 2 (3+1) = 25cm, SO25*75*300=562500 cubic cm
