Lesson 6-2 Volume of Prisms and Cylinders Obj: I can find the volume of prisms and cylinders HWK: p 270 1-6 all, 10, 12 Vocab: 1) prism 2) cylinder
Formulas: Volume Prism: Rectangular Prism Triangular Prism V= Bh V = Bh V = Bh B = area of base V = lwh V =( 1 2 bh)h h = height of prism Cylinder: V = Bh B = area of base h = height of cylinder V = πr²
Find the volume of each figure to the nearest tenth. Use 3.14 for π. Ex 1) 7 m 5 m 2 m
Ex 2) 4 in 12 in
Ex 3) 7 ft 5 ft 6 ft
Ex 4) A cereal box measures 9 in by 2 in by 6 in Ex 4) A cereal box measures 9 in by 2 in by 6 in. Explain what happens to the volume of the box if the length, the width or the height is doubled.
Ex 5) A juice can has a radius of 2 in and a height of 5 in Ex 5) A juice can has a radius of 2 in and a height of 5 in. Explain whether tripling the height of the can would have the same effect on the volume as tripling the radius.
