FORMULA SHEET v=Bh l x w Rectangular Prism: Triangular Prism: Triangular Prism:
What is It?!?! • Volume- The number of cubic units needed to ____________ a space • Volume is measured in: fill Cubic units
Goal for today Volume Pyramids
Discovery Can you discover the rule?
Pyramid and Cone v=1/3Bh What does this formula look like?
Important Comparisons A Pyramid is 1/3 the size of a Prism with the same Base. A Coneis 1/3 the size of a Cylinderwith the same Base.
Pyramid and Cone v=1/3Bh B= Base Base depends on what kind of base the shape has: Rectangular Pyramid: l x w Triangular Pyramid: 1/2bh
#1 Find the volume of the pyramid to the nearest tenth. Estimate to check whether the answer is reasonable. 1 3 V = Bh Use the formula. 4 ft Find the area of the rectangular base. B = 5 · 7 = 35 1 3 V = · 35 · 4 Substitute for B and h. 7 ft 5 ft Multiply. V ≈ 46.7 ft3 1 3 V = Round the measurements. · 30 · 5 Estimate The answer is reasonable. V = 50 ft3
1 3 ·52 ·6 · ≈ 1. V ≈ Find the volume of the cone to the nearest tenth. Use 3 for . Estimate to check whether the answer is reasonable. 1 3 Use the formula. The base is a circle so B = ·r2 3.14 · 52 78.5. Bh V = 1 3 Substitute for B and h. · 78.5 · 6 V V 157 yd3 Multiply. 1 3 Estimate 150 yd3 The answer is reasonable.
