    Default After the name of a geometric shape please

    A square box with a sloped bottom much like a town council swiming pool.

    Im concreting & i need to work out my vol req. Basic square but sloped bottom..ie 320mm at one end & 140 mm at the other.(long story but sloping ground)

    Once i get the name of that shape.. im sure i can google the rest of the answer but i simply cant find its correct name.

    Imagine your swimming pool

    Vol = (depth at shallow end + depth at deep end) * .5 * length of pool * width of pool

    good luck
