A prism is not so much a concept in algebra, but a geometric shape.
A rectangular prism has 12 edges.
Pretty much everything
a triangular prism, square based pyramid, rectangular prism and much more
The volume of the prism is three times as much as that of the prism.
Do you mean, what is the volume of a (right) triangular prism? Multiply the area of one end by the length of the prism.
Two are needed at each end of the prism
There is no limit to the number of cubes which can be arranged on top of a rectangular prism.
