AND CYLINDERS
Find the volumes of prisms and cylinders.
Volume
# of cubic units it takes to fill a three
dimensional shapes
Units will be cubed
To
the third power
Prism
Solid with two parallel and congruent polygonal
faces called bases.
Named by the shape of its base.
Volume of Prisms
V = Bh
“B” is the AREA of the base
Example
Find the volume of the triangular prism.
V = Bh
1
V = (2 bh) h

V =( • 4 • 9) 10
2
V = (2 • 9) 10
V = (18) 10
