After the name of a geometric shape please
A square box with a sloped bottom

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.

A cube + a triangular prism

Imagine your swimming pool
Vol = (depth at shallow end + depth at deep end) * .5 * length of pool * width of pool
good luck
