Prisms

2. Prism Formula
Even though there are three different types of prisms, there is only one formula: V = Bh
h = height (the distance between bases)
B = area of the base
**B does not represent base, but the area of the base; therefore, you must figure out the area of the base using area formulas.

3. Types of Prisms
Prisms have two bases and are defined by what shape their bases are. If the bases are rectangular, then it is a rectangular prism. If the bases are circular, then it is a cylinder. If the bases are triangular, then it is a triangular prism.

4. Rectangular Prism V = Bh B = bh B = bh B = 9(5) B = 45 in2 V = Bh
V = 135 in2

5. Triangular Prism V = Bh B = 1 2 bh B = 1 2 bh B = 1 2 (4)(6)
B = 12 cm2
V = Bh
V = 12(12)
V = 144 cm2

6. Cylinder V = Bh B = πr2 B = πr2 B = 3.14(82) B = 3.14(64)
B = units2
V = Bh
V = (21)
V = 4, units3

7. Practice Solve the volumes of the figures below
V = Bh
V = 3.14(52)(12)
V = 942 cm3
V = Bh
V = 10(4)(10)
V = 400 m3
V = Bh
V = 3.14(42)(15)
V = cm3
V = Bh
V = 1 2 (4)(6)(8)
V = 96 cm3
V = Bh
V = 1 2 (3)(4)(7)
V = 42 ft3
