# A soft drink is available in two packs - (i) a tin can with a rectangular base of length 5 cm and width 4 cm, having a height of 15 cm and (ii) a plastic cylinder with a circular base of diameter 7 cm and height 10 cm. Which container has greater capacity and by how much?

**Solution:**

Since the tin can is cuboidal in shape while the other is cylindrical, we will find the volume of both containers.

The volume of a cylinder of base radius, r, and height, h = πr^{2}h

The volume of a cuboid of length ' l ', breadth ' b', and height ' h ' = l × b × h

Dimensions of tin can with a rectangular base are:

Length of the cuboidal tin can, l = 5cm

The breadth of the cuboidal tin can, b = 4cm

Height of the cuboidal tin can, h = 15cm

The volume of the cuboidal tin can = l × b × h

= 5 cm × 4 cm × 15 cm

= 300 cm^{3}

Dimensions of the plastic cylinder with a circular base are:

The diameter of the cylindrical plastic can = 7 cm

The radius of the cylindrical plastic can, r = 7/2 cm

Height of the cylindrical plastic can, h = 10cm

The volume of the cylindrical plastic can = πr^{2 }h

= 22/7 × 7/2 cm × 7/2 cm × 10cm

= 385 cm^{3}

Clearly, the plastic cylinder with a circular base has greater capacity than the tin container.

Difference = 385 cm^{3} - 300 cm^{3} = 85 cm^{3}

The plastic cylindrical has more capacity than the tin can by 85 cm^{3}.
