SURFACE AREA AND VOLUME

OBJECTIVES• Introduce the idea of surface area and volume• Apply understanding of area to surface area• Apply surface area and volume

WHAT IS SURFACE AREA?• Surface area is the sum of all the areas of all the

shapes that cover the surface of an object.

FORMULAS FOR SURFACE AREA• Surface area of a rectangular prism = 2lw + 2lh + 2wh• Surface area of a triangular prism= area of the top and bottom plus area of each side

VOLUME• Volume is the amount of 3-dimensional space

occupied by an object.• It is measured in cubic units.• Volume of a rectangular prism = lwh• Volume of a triangular prism= (1/2bh)(H)
