Q.2. Take 3 dice of side 1cm. Keep these together as shown 1 1 cm 1 am 1 cm 1cm 11cm 1 Find the surface area and volume of all cubes separately and also find volume of the cuboid formed​

Answer 1

Answer:

The surface area of all the cubes = 6 cm²

The volume of all the cubes = 3 cm³

The volume of the cuboid = 3 cm³

Step-by-step explanation:

Given:

3 ludo dice of sides 1 cm each

To find out:

The surface area and volume of each cubes and the volume of cuboid formed by joining the 3 dices edge to edge

Solution:

We know that, if a cube has its side as a

Then its volume is given by a^3a3

And its surface area is given by 6a^26a2

Thus,

The volume of each of the 3 cubes = 1^313 cm³

                                                           = =1=1 cm³

The surface area of each of the 3 cubes

= 6\times 1^26×12

= 6 cm²

The cuboid formed by joining the cubes edge to edge will have its

Length L = 1 + 1 + 1 = 3 cm

Breadth B = 1 cm

Height H = 1 cm

Therefore, the volume of the cuboid

= L × B × H

= 3 × 1 × 1

= 3 cm³
