**Solution:-**

The given net can be folded as cube.

Because, it can be folded as below,

**Solution:-**

The given net cannot be folded as cube.

Because, it can be folded as below,

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

By observing the above figure the sum of the opposite faces is equal to 7.

So, the given net can be folded into a net of dice.

**(ii)**

No, this cannot be a net for a die.

By observing the figure we can say that, one pair of opposite face will have 1 and 4, another pair of opposite face will have 3 and 6 the sum of these two opposite faces are not equal to 7.

**4. 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.)**

Because, the net (iii) can be folded as cylinder.

**(c) (iv)**

Solution:-

**Solution:-**

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

**Solution:-**

From the question it is given that dimension of a cuboid are 5 cm, 3 cm, and 2 cm.

The three different isometric sketches of this cuboid is shown below,

1

2

**3. 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.**

**Solution:-**

Oblique sketch

Isometric sketch

**5. Give (i) an oblique sketch and (ii) an isometric sketch for each of the following:**

**(a) A cuboid of dimensions 5 cm, 3 cm and 2 cm. (Is your sketch unique?)**

**(b) A cube with an edge 4 cm long.**

**Solution:-**

(a)

**(i) **Oblique sketch

**(ii)** Isometric sketch

**(ii)** Isometric sketch
