Grade 6 | Unit 1 | Lesson 15: More Nets, More Surface Area | Practice Problems

Jada drew a net for a polyhedron and calculated its surface area. Description: Triangular prism, Faces are: 5 by 4 rectangle, area 20 square centimeters. 4 by 4 square, area 16 square centimeters, 2 triangles, bases of 5, heights of 3, areas of 12 square centimeters each, and 3 by 4 rectangle, area = 12 square centimeters. What polyhedron can be assembled from this net? Jada made some mistakes in her area calculation. What were the mistakes?

• Cube

• Triangular prism

• Sphere

• Cylinder

• Rectangular prism
