1. Chapter 10: Surface Area and Volume Objectives: Students will be able to find the surface area and volume of three dimensional figures.

2. Cross Section The shape you get when you “slice” a 3 dimensional figure

3. VOLUME The space that a figure occupies Measured in cubic units When finding volume of pyramids and cones, need to use the height, not slant height. The height is perpendicular to the base.

4. VOLUME FORMULAS: Right Rectangular Prism: Any Pyramid: V= lwh Any Right Prism:B = area of the base V= Bh B= area of the baseCone: Cylinder: Square Pyramid:Sphere:
