Volume of Prisms and Cylinders Volume = (Area of base)(Height) The volume of a 3-dimensional figure is the measure of space it occupies. It is measured by cubic units. Ex: centimeters cubed (cm³)
Rectangular Prism V = (Area of base)(h) V = (Lw)(h) 5 cm 4 cm 3 cm Example 1: Find the volume of the rectangular prism shown above. V = l(w)(h) V = 5(4)(3) V = 60 cm³
Triangular Prism V = (Area of base)(height) V = (½bh)(height) Example 2: Find the volume of the triangular prism shown above. V = (½bh)(height) V = ½(3)(4)(2) V = 12 in³
Cylinder V = (Area of base)(h) V = ( r 2 )(h) Example 3: Find the volume of the cylinder shown above. Round your answer to the nearest hundredth. V = ( r 2 )(h) V = (8 2 )(12) V = 768 V ≈ 2412.74 in 3
