Large Square Prism Small Rectangular Prism Large Rectangular Prism Hexagonal Prism Large T riangular Prism Small T riangular Prism Square Pyramid T riangular Pyramid Sphere Cone Cylinder Hemisphere V =A x H V = (s x s) x H V = (4.6)(4.6)(4.6) V = 97.3 cm 3 V =A x H V = (1 x w) x H V = (2 x 2) x 4.
3 Intr oduction The transparent Power Solids™ set includes 12 plastic three-dimensional shapes that allow for hands-on study of volume. Power Solids can be integrated easily with daily math lessons for introducing, teaching, and reviewing math concepts effectively .
Ask students how they might organize the shapes into categories based on their features. W rite students’ answers on the board. Then, define pyramids and prisms . Hold up an example of a prism and a pyramid for the class. Encourage students to organize the Power Solids again based on this information.
5 Intr oducing V olume V olume , or the capacity of an object, is sometimes confused with surface area. At first glance, the formulas appear somewhat similar . A helpful way to compare the concepts is to explain surface area as the amount of room on the outside of a shape, and volume as the amount of space inside a shape.
V olume Formulas Prism Finding the volume of a general prism is a matter of multiplying the area of the base times the height of the prism: V olume g eneral prism = A x H Identify the variables: A = Area of the base H = Height of the prism The formula for the area of the base of the prism depends upon the shape of the base.
Hexagonal Prism V olume hexagonal prism = A x H Identify the variables: A = Area of the hexagonal base H = Height of the prism Explain that the area for a hexagon is calculated as follows: A = w x 3 /.
