Nets and Surface Area

Identify polygons that compose a net.

(A). RIGHT PRISM

  • Move the slider up and down to see the nets of a right prism.​

(B). CUBE

  • Drag the squares to form nets of a cube.​ See example on the left.

(A). Each of the nets can be assembled into a polyhedron. Match each net with its corresponding polyhedron, and name the polyhedron. Explain how you know the net and polyhedron go together.

(1). Name each polyhedron.

(2). Explain how you know each net and polyhedron go together.

(B). The applet below have three nets that would form different polyhedra.

(1). Name the polyhedron that each net would form when assembled.

(2). Find the surface area of each polyhedron.

(3). Explain how you found the surface area of each polyhedron. Use the applet below if you need help. (Just click on the double arrow and move the slider.)

(A). Study the net below and answer the following questions.

Can this net be assembled into a cube? Explain how you know. Label parts of the net with letters or numbers if it helps your explanation.

(B). Here below are two nets. Mai said that both nets can be assembled into the same triangular prism.

Do you agree? Explain or show your reasoning.

For each net, decide if it can be assembled into a rectangular prism.

For each net, decide if it can be folded into a triangular prism.
