    单选题
    A rectangular fish tank has a base 2 feet wide and 3 feet long. When the tank is partially filled with water, a solid cube with an edge length of 1 foot is placed in the tank. If no overflow of water from the tank is assumed, by how many inches will the level of the water in the tank rise when the cube becomes completely submerged?
    A

    1/6

    B

    1/2

    C

    2

    D

    3

    E

    4


    正确答案： C
    解析：
    When a solid cube with an edge length of 1 foot is placed in the fish tank, it displaces a volume of water that is equal to the volume of the cube, which is 1×1×1 or 1 cubic foot. If h represents the change in the number of feet in the height of the water in the fish tank, then
    Volume of displaced water = 2×3 ×h = 1
    h = 1/6 foot
    Hence, the number of inches the level of the water in the tank will rise is 1/6 ×12 or 2.
