Chapter 10: Surface Area and Volume Objectives: Students will be able to find the surface area and volume of three dimensional figures.
Prism: 2 congruent, parallel faces (called the bases). The other faces of the prism are called lateral faces Named by the shape of its base Altitude: perpendicular segment joining the bases Height: the length of the altitude
Lateral Surface Area: The sum of the areas of the lateral faces Area of the sides (not including the bases) For a Right Prism: LA = ph p=perimeter of base h= height
Surface Area: Sum of lateral surface area and the area of the 2 bases Find lateral surface area and then add the area of the bases For a Right Prism: SA= LA + 2B B= area of the base So… SA = ph + 2B
Examples: Find LA and SA for each figure. Round to nearest tenth, if necessary. 1.2.
Find the LA and SA of the trapezoidal prism. Area of a trapezoid:
