1. Determining the Appropriate Type of Measure PSSA Coach Lesson 13

2. PA Standards B.2.2.3 Determine the appropriate type of measurement (circumference, perimeter, area, surface area, volume) for a given situation (e.g., which measurement is needed to determine the amount of carpeting for a room).

3. lPerimeter and circumference are the distance around a l Perimeter and circumference are the distance around a figure. they are measured in units of length, such as feet or centimeters. *Area is the region that a two-dementional figure covers * Area is the region that a two-dementional figure covers or encloses. It is measured in square units, such as square inches (or in 2 ). 4m 6m 4m A = L x W P = 2L + 2W

4. lSurface area is the total area of the surfaces of a three- l Surface area is the total area of the surfaces of a three- dementional figure. Like area, it is measured in square units. *Volume is the amount of space a three-dementional figure * Volume is the amount of space a three-dementional figure encloses. It is measured in cubic units, such as cubic feet or (ft 3 ). V = L x W x H
