  1. a. ANSWER The volume is192 cubic inches. Finding Volumes of Prisms EXAMPLE 1 Find the volume of the prism. Base is a rectangle with arealw. V = Bh = lwh = 12(8)(2) = 192

  2. b. 1 (4)(3)(10) = 2 ANSWER The volume is 60 cubic meters. Finding Volumes of Prisms EXAMPLE 1 1 Base is a triangle with areabh. 2 V = Bh = 60

  3. Find the volume of the cylinder. ≈ 254.469 Finding the Volume of a Cylinder EXAMPLE 2 SOLUTION The radius is one half the diameter, so r = 3cm. V = Bh Write formula for volume. = πr2h Write formula for volume of a cylinder. = π(3)2(9) Substitute 3for rand 9 for h. = 81π Simplify. Evaluate using a calculator.

  4. Finding the Volume of a Cylinder EXAMPLE 2 ANSWER The volume is about 254 cubic centimeters.
