Dice are cubes with dots on each face. Opposite faces of a die always have a total of seven dots on them.

Here are two nets to make dice (cubes); the numbers inserted in each square indicate

the number of dots in that box.

Insert suitable numbers in the blanks, remembering that the number on the

opposite faces should total to 7.

Can this be a net for a die?

Explain you answer

Here is an incomplete net for making a cube. Complete it in at least 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.)

Match the nets with appropriate solids:

a | 1 | ||

b | 2 | ||

c | 3 | ||

d | 4 |

A bulb is kept burning just right above the following solids. Name the shape of the shadows obtained in each case. Attempt to give a rough sketch of the shadow. (You may try to experiment first and then answer these questions).

Here are the shadows of some 3−D objects, when seen under the lamp of an overhead projector. Identify the solids (s) that match each shadow. (There may be multiple answers for these!)

Examine if the following are true statements:

1) The cube can cast a shadow in the shape of a rectangle.

2) The cube can cast a shadow in the shape of a hexagon.
