Insert suitable number in the blanks, remembering that the number on the opposite faces should total to 7.

Question 3 : Can this be a net for a die? Explain your answer.

Question 4 : Here is an incomplete net for making a cube. Complete it in atleast two different ways. Remember that a cube has six faces. How many are there in the net here? (Give two separate diagrams. If you like, you may use a squared sheet for easy manipulation).

Question 5 : Match the nets with appropriate solids:
