Surface Area Nets & Rectangular Prisms
Rectangular Prisms Made of 6 sides Top & Bottom Front & Back Left & Right
Nothing but Net! A net is the pattern to make a box. Notice this net will fold up to make the box.
This one too! The net will fold up to create the box.
Surface Area of a Net Find the area of each rectangle. 8 8 32 16 Add them up! 32 16 8 112 +
What about boxes? Find the area of each side (rectangle) add them together
Use the Formula 2(l W) + 2(W h) + 2(l h) or SMILE!! Length x Width x Height To find the surface area
Smiley Face Method Multiply l x w Multiply w x h Multiply l x h Length x Width x Height This gives you the area of the Top the Side the Front ADD ‘ EM UP!!!
You’re Not Done Yet! Since a box has six sides and you’ve only found three sides, you have to double your answer.
It makes no difference The surface area of a net is the SAME as the surface area of the box.
Check it out! 3 x 2 = 6 2 x 6 = 12 3 x 6 = 18 Adds to 36 cm 2 Double it! 72 cm 2 12 18 6 6 Add ‘em up! 72 cm 2 They are the SAME!!!
Finding Surface Area Step 1: Flatten the 3-D figure A rectangular prism will flatten to 6 rectangles. Depending on the dimensions of the 3-D figure, you.
Finding Surface Area Rectangular Prism Step 1: Flatten the 3-D figure
Triangles, Quadrilaterals, Nets, Prisms & Composite Polygons
Vocabulary Area Surface AreaVolume More vocabulary.
The surface area of a prism is the entire area of the outside of the object. To calculate surface area, find the area of each side and add them together.
Surface Area: Prisms and Pyramids
EXAMPLE 1 Use the net of a prism Find the surface area of a rectangular prism with height 2 centimeters, length 5 centimeters, and width 6 centimeters.
Warm Up Find the perimeter and area of each polygon. Show work and include units! in 6 in 5 in 25 m 20 m 12 m 13 m 14 cm 11 cm 8 cm.
Warm-up Find the area of the following: show calculations! 1.)2.) 3.) 4 inches 8 ft 12 cm 8ft 3 cm 3 inches.
Volume and Surface Area of a Triangular Prism. A triangular prism is a three- sided polyhedron with two parallel triangular bases and three rectangular.
