Detailed procedures:. A chart can be drawn on board with formulas and dimensions for each shape for comparison of shape dimensions. Label volume on one column and Surface area on second column. The first row can say triangle, while the second can say rectangle. The third row can have rectangular prism and the fourth row can be labeled triangular prism. Students can take turns either walking up to board to fill in the formulas or raise their hand to answer questions, such as how do we find the area of a triangle or how do we find the volume of a rectangular prism.

Ask students to draw one centimeter approximately squares on the image and have them count the number of squares that fit on the rectangular sides and triangular sides these 2 triangular sides are to have the same number of squares and label the quantity on each side.

Mention that at least two rectangular sides are to have the same number of squares isosceles triangular prism. May want to mention to students that very small squares will take a long time to draw and count and that smaller squares could be drawn at home.

Ask students to complete the formula for surface area of a three-dimensional figure by combining knowledge of a one flat two-dimensional figure. Discuss prior knowledge of volume of rectangular prism and ask them to combine their knowledge on the area of a rectangle to find the surface area of a rectangular prism.

Discuss when finding the volume of an object or surface area may be necessary, such as painting a room, mailing a package, or liquid containers, material for a tent. For Surface Area:. How many square feet will be painted if a room has walls that measure 8 ft. Can also ask them to subtract three doors that measure 3ft. For Volume:. How much strawberry yogurt will fit into a 3 inch x 2 inch x 6 inch triangular prism container and compare to a 4 inch x 5 inch x 1 inch rectangular prism container, and which one holds more yogurt?

Length is a one-dimensional attribute of a geometric figure. We measure lengths using units like millimeters, centimeters, meters, kilometers, inches, feet, yards, and miles. Area is a two-dimensional attribute. We measure area in square units. Volume is a three-dimensional attribute. We measure volume in cubic units. For example, a cube that is 1 kilometer on each side has a volume of 1 cubic kilometer. Surface area and volume are different attributes of three-dimensional figures. Surface area is a two-dimensional measure, while volume is a three-dimensional measure.

Draw a pentagon five-sided polygon that has an area of 32 square units. Label all relevant sides or segments with their measurements, and show that the area is 32 square units.
