A prism in mathematics is a figure that has the same cross-sectional shape no matter where it is cut. That doesn't really explain it well but a pipe is a cylinder with a circular base so it is a prism. A Toblerone, the triangular chocolate, is a triangular prism (almost). A box, a crate, a rectangular sky scraper is a rectangular prism.
They all have a volume = area of base x height.
rectangular prism
length x width x height
The volume of a rectangular prism can be found by the formula: volume=length*width*height
Volume = (length) times (width) x (height)
V = l × w × h
V = Ah/3
A person can find the volume of a prism by 1/2 x length x width x height. This formula works for a triangular prism.
The Area of its base times the height of the shape.
Area=Bh when B=area of the base, and h=height of the prism/cylinder
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
Volume for a rectangular or square prism= length x height x width
bwh base times width times hight
Base times height divided by two times length
area of base x height area of base x height
