## formulas for prisms and cylinders

For a rectangular prism big b equals the length times the width. For a triangular prism the big b equals (bh/2) or ½bh. H equals the height of the prism or cylinder. H also means the number of layers. The big B also means the number of cubic units in the first layer. The formula for volume of any prism is V=Bh. All prisms are named after the shape of their base.
