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. What polyhedron can be assembled from this net?

• Triangular prism

• Cube

• Rectangular prism

• Cylinder

• Pyramid

Jada drew a net for a polyhedron and calculated its surface area. Jada made some mistakes in her area calculation. What were the mistakes?

• She incorrectly calculated the areas of the triangular faces.

• She added the areas incorrectly.

• She miscalculated the area of the rectangle.

• She used wrong units.

• No mistakes were made.

Jada drew a net for a polyhedron and calculated its surface area. Find the surface area of the polyhedron. Show your reasoning.

A cereal box is 8 inches by 2 inches by 12 inches. What is its surface area? Show your reasoning.

Twelve cubes are stacked to make this figure. What is its surface area?

• 36 square units

• 40 square units

• 44 square units

• 48 square units

• 52 square units

Twelve cubes are stacked to make this figure. How would the surface area change if the top two cubes are removed?

• Decrease by 6 square units

• Decrease by 8 square units

• Decrease by 10 square units

• No change

• Increase by 2 square units

Here are two polyhedra and their nets. Label all edges in the net with the correct lengths.

What three-dimensional figure can be assembled from the net?

• Square pyramid

• Cube

• Rectangular prism

• Cylinder

• Cone

What is the surface area of the figure? (One grid square is 1 square unit.)
