Volume
Volume �The volume of a solid is the amount of space it occupies. �Volume is measured in cubic units. �Ex: cubic feet or ft 3 �Why is it measured in cubic units? �The volume of a prism is the product of the area of the base (B) and the height. �V = areabase x height
Volume of Rectangular Prisms Formula: V = Bh V = lwh • Example: V = Bh V = lwh V = (3)(4)(6) V = (12)(6) V = 72 in 3 6 in 3 in 4 in
Volume of Rectangular Prisms 3 in 10 cm 2 in 5 in V = Bh V = lwh V = (5)(2)(3) V = (10)(3) V = 30 in 3 10 cm V = Bh V = lwh V = (10)(10) V = (100)(10) V = 1000 cm 3
Volume of Triangular Prisms
Volume of Triangular Prisms �Formula: V = Bh V = (½bh)h • Example: V = Bh V = (½bh)h V = ½(2)(5)(7) V = (5)(7) 2 cm 3 V = 35 cm m 7 c

Real Life Application Mrs. Pence is enlarging the patio in her back yard. Look at the diagram of the existing patio and calculate how many cubic yards of concrete is needed to make it the proposed size. 3 ft 12 ft 3 ft Patio 20 ft 3 ft HOUSE concrete depth: 6 inches.
Tower of Pisa in Pisa, Italy About 56. 70 m high Diameter of base: About 15. 484 meters The Leaning Tower of Pisa is a bell tower in Pisa Italy. Construction started in 1173 and went on for over 177 years. The tower started to lean shortly after construction started due to poorly laid foundation. The tower leans toward the southwest at a 3. 99 degree angle. Classify Solid: Cylinder Surface Area: S = 2 B + Ch S = 2πr 2 + 2πrh S = 2π(7. 742)2 + 2π(7. 742)(56. 7) S = 2π(59. 94) + 2π(438. 97) S ≈ 376. 42 + 2756. 73 S ≈ 3133. 15 m 2 Volume: V = Bh V = πr 2 h V = π(7. 742)2(56. 7) V = π(59. 94)(56. 7) V ≈ 10671. 6 m 3
