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 of 7.

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

How many vertices does a cuboid have?

Write the number of faces, edges and vertices in the solids given below:
Prism

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

Using an isometric dot paper, draw the solid shape formed by the given net.

The following diagrams show the nets of various solids. Name the solids.

Mention the number of edges in a triangular prism.

How many faces are there in a triangular pyramid?

What will be the base of a square pyramid?

If a cone of base radius 3 cm is placed on a cylinder of base radius 3 cm, then how many faces will the resultant figure have?

Use isometric dot paper and make an isometric sketch for each one of the given shapes

The dimensions of a cuboid are 5 cm, 3 cm and 2 cm. Draw three different isometric sketches at this cuboid.

Three cubes each with 2 cm edge are placed side by side to form a cuboid. Sketch an oblique or isometric sketch of this cuboid

If we rotate a right angled triangle of height 5 cm and base 3 cm about its height a full turn, we get

Looking at the following object from the side, what will be the view?

Take a square piece of paper as shown in fig. (i). Fold it along its diagonals as shown in fig. (ii). Again, fold it as shown in fig. (iii). Imagine that you have cut-off 3 pieces of the form of congruent isosceles right-angled triangles out of it as shown in figure 4
