11.4 Volumes of Prisms and Cylinders
Volume is the space a figure occupies. Measured in cubic units. Volume of a cube: V = s3 Cavalieri’s Principle If two space figures have the same height and the same cross-sectional area at every level, then they have the same volume.

Volume of a Prism The volume of a prism is the product of the area of the base and the height of the prism. V = Bh

Finding the Volume of a Rectangular Prism
What is the volume of the Rectangular Prism? V = Bh V = (24)(20)(10) V = 480 (10) V = 4800 cm3

Finding the Volume of a Triangular Prism
What is the approximate volume of the triangular prism?

Volume of a Cylinder The volume of a cylinder is the product of the base and the height of the cylinder.
