    Does the tank or the water rise? Your question doesn't make that clear.

    the water rises

    the change in the volume of the water in the tank equals the volume of the stone

    so volume change = Pi(r^2)h, where r is the radius and h is the height
    so V = Pi(24^2)(1.5) cu inches
    = appr. 2714 cu inches.

    24 inches isn't that the diameter
