Question

If a cubical container of length, breadth and height each of 10 cm can contain exactly 1 litre of water, then a spherical container of radius 10.5 cm can contain (a) not more than 4 litres of water (b) more than 4 litres but less than 4-5 litres of water (c) more than 4-5 litres but less than 5 litres of water (d) more than 5 litres of water

Answer 1

Answer:

Step-by-step explanation:

Given a = 10cm

Volume of cube = a³=10×10×10=1000cm³= 1 litre

Radius,r = 10.5cm

Volume of sphere = 4/3πr³=4/3×22/7×10.5×10.5×10.5= 4851cm³

1000cm³=1 litre

1000cm³×4.851= 1 litre×4.581

4851cm³=4.851 litres

Therefore, the spherical container can contain (c) more than 4.5 litres but less than 5 litres
