**6. Show some differences between capacity and volume.**

(a) Capacity:

The ability of an object to contain a substance that is either solid, gas or liquid is termed as capacity.

The other definition is, it is the amount of the potential of a substance that an object is able to hold.

The SI units of capacity are gallons, litres, etc.

Capacity is found in hollow objects.

(b) Volume:

The total amount of space covered by the object is known as volume.

It is defined as the actual amount of an object that covers a definite space.

The SI unit of volume is cubic metres or cubic centimetres.

Volume is found in both solid and hollow objects.

**7. Write down the surface areas of the cylinder, cuboid and cube.**

(a) Cube – The surface area of the cube is 6 * a^2.

(b) Cuboid –2 (lb + bh + hl) is the total surface area.

Here l is the length, b is the width and h is the height.

(c) Cylinder –2πrh is the curved surface area.

The total surface area of the cylinder is 2πr(h + r)

Here, r denotes the radius of the base and h is the height of the cylinder.

**8. How can you say that area and perimeter are different?**

(a) Perimeter:

The boundary or outline of the shape of an object is known as the perimeter.

The perimeter is measured in linear units.

The perimeter is the sum of the length of all the sides of the object.

For example, the perimeter of a square of length 10cm is 40cm.

(b) Area:

The total space occupied by the object or the shape is called the area.

It is measured in square units.

For example, the area of the park which is square-shaped, 20cm long is 400 sq. cm.
