    Amount of Water in Tank 4x3x5 feet?

    A sealed tank 4 feet hight with width 3 feet and length 5 feet is filled one foot deep with water. If the tank is turned on one of its smallest faces, how deep (in feet) will the water be?

    I can only try and draw a picture...but that doesn't help me in any way solve the problem. To the experts I look to :-)

    The volume of water in the tank is 3x5x1 cubic ft.

    Now the tank is turned on its side and if the depth of water is D, we have
    the volume of water is:

    V = 3x4xD = 15 cubic ft,

    so: D = 15/(3x4) =1.2 ft.

    Stuck at 1st step

    I don't understand how you get the volume of water to be

    3*5*1 cubic feet

    What formula is that for? Don't understand where the one comes from.

    Also V= l*w*h

    Sorry Captain Black. Just trying to make sure I am able to do these "types" of problems in general as supposed to just getting the answers. You are major help and a pro I tell you.

    The width of the tank is 3ft, the length is 5 ft and it is filled to a depth of 1 ft, so the volume of water is 3*5*1 cubic ft.

    When it is turned on end we have the plan size is now 4 by 3 ft, and if the depth is D the volume of water is 4*3*D which is equalk to the volume we had before.
