1 11.4 Volumes of Prisms and Cylinders Volume is the space a figure occupies.Measured in cubic units.Volume of a cube: V = s3Cavalieri’s PrincipleIf two space figures have the same height and the same cross-sectional area at every level, then they have the same volume.
2 Volume of a PrismThe volume of a prism is the product of the area of the base and the height of the prism.V = Bh
3 Finding the Volume of a Rectangular Prism What is the volume of the Rectangular Prism?V = BhV = (24)(20)(10)V = 480 (10)V = 4800 cm3
4 Finding the Volume of a Triangular Prism What is the approximate volume of the triangular prism?
5 Volume of a CylinderThe volume of a cylinder is the product of the base and the height of the cylinder.
6 Finding the Volume of a Cylinder What is the volume of the cylinder in terms of pi?
