**1. Match the following shapes with their names:**

**Solution:-**

**2. Identify the nets which can be folded to form a cube (cut out copies of the nets and try it)**

**(i) **

**Solution:-**

The given net cannot be folded as cube.

Because, it can be folded as below,

**(ii) **

**Solution:-**

The given net can be folded as cube.

So, it can be folded as below,

**(iii) **

**Solution:-**

The given net can be folded as cube.

So, it can be folded as below,

**(iv)**

**Solution:-**

The given net can be folded as cube.

So, it can be folded as below,

**(v)**

**Solution:-**

The given net cannot be folded as cube.

Because, it can be folded as below,

**(vi)**

**Solution:-**

The given net can be folded as cube.

So, it can be folded as below,

**3. 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.**

**Solution:-**

**(i)**

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)**

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.

**4. Can any of the following be a net for a die? If no, explain your answer.**

**(i)**

**Solution:-**

Yes

**(ii) **

**Solution:-**

The given net is folded as dice is shown in figure below,

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.

**5. 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? (You may use a squared paper for easy manipulation).**

**Solution:-**

In the given net there are 3 faces and it can be completed as shown below,

**6. The dimensions of a cuboid are 5 cm, 3 cm, and 2 cm. Draw three different isometric sketches of this cuboid with height(i) 2 cm(ii) 3 cm(iii) 5 cm**

**Solution:-**

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

(i) 2 cm

(ii) 3 cm

(iii) 5 cm

**7. Give (i) an oblique sketch (ii) an isometric sketch for each of the following:(a) A cube is with an edge 4 cm long.(b) A cuboid of length 6 cm, breadth 4 cm, and height 3 cm.**

**Solution:-**

**(a)**

(i) Oblique sketch

**(ii)** Isometric sketch

**(b) A cuboid of length 6 cm, breadth 4 cm, and height 3 cm.**

(i) Oblique sketch

**(ii)** Isometric sketch
