1. DO NOW 11 in. 1.Name the solid. 2.Find its surface area. 7 in. 5 in. 6 in. Triangular prism 244 in. 2

2. What is “slant height?”

3. You need to calculate how much material is needed to cover this box. How could you do that?

4. You need to calculate the area of each side. One side‘s area can be found by multiplying 17 by 17. Since there’s 6 sides, the answer is 1734 square cm.

5. 1.Draw a net 2.Find the area of each face. 3.Add the areas to find the surface area to determine how much wrapping paper is needed to cover this box. 6 x 2 x 2 = 24 2 x 3 x 2 = 12 6 x 3 x 2 = 36 Added all together = 72 square cm

6. 1.Draw a net 2.Find the area of each face. 3.Add the areas to find the surface area to determine how much paint is needed to cover this pizza box. 5 x 2 x 2 = 20 12 x 5 x 2 = 120 12 x 2 x 2 = 48 Added all together = 188 in²

7. 1.Draw a net 2.Find the area of each face. 3.Add the areas to find the surface area to determine how much plastic is needed to make this tiny tarp. ½ (15 x 10) = 75 x 2 = 150 20 x 10 = 200 20 x 20 x 2 = 800 Added all together = 1150 cm²

8. 1.Draw a net 2.Find the area of each face. 3.Add the areas to find the surface area to calculate how much glass is needed to make this small figurine. ½(12 x 8) = 48 x 4 = 192 12 x 12 = 144 Added together = 336 in²

9. 1.Draw a net 2.Find the area of each face. 3.Add the areas to find the surface area to calculate how much glass is needed to make this small figurine. Base: 1/2(6 x 5.2) = 15.6 Lateral (side) faces of pyramid: ½ (6 x 8.3)= 24.9 x 3= 74.7 Added all together = 90.3 m²

10. 1.Draw the net. 2.Find the area of each face. 3.Add the areas to find the surface area. The outside of a cube-shaped box is covered in velvet. If each side is 3 inches, how much velvet is needed to cover the box? 3 x 3 x 6 = 54in²

11. 1.Draw the net. 2.Find the area of each face. 3.Add the areas to find the surface area. The outside of a cube-shaped box is covered in velvet. If each side is 3.5 inches, how much velvet is needed to cover the box? 3.5 x 3.5 x 6 = 73.5 in²

12. 1.Draw the shape. 2.Draw the net 3.Find the area of each face. 4.Add the areas to find the surface area. How much cardboard is needed to make a shipping box that is 7 inches long, 10 inches wide, and 5 inches high? 310in²

13. 1.Draw the net 2.Find the area of each face. 3.Add the areas to find the surface area. A triangular pyramid made of equilateral triangles each having a height of 12 cm and a base of 2 cm. What is its surface area? ½(12 x 2) = 12 x 4 = 48 cm²
