Formulas Prism b = Area of base h = height V = b ∙ h (rectangular or triangular) b = Area of base h = height V = b ∙ h Cylinder b = base (pr2) h = height V = b ∙ h V = (pr2) ∙ h

Example 1 Find the volume of a rectangular prism with base 2 cm by 5 cm and height 3 cm.

Example 2 Find the volume of the figure to the nearest tenth.

Example 3 Find the volume of the figure to the nearest tenth.

Cone b = base (pr2) h = height V = b ∙ h V = ⅓(pr2) ∙ h Pyramid (triangular or rectangular) b = Area of base h = height V = ⅓b ∙ h Cone b = base (pr2) h = height V = b ∙ h V = ⅓(pr2) ∙ h
