Dev is a 12-year-old, studying in 6th class, and has a younger brother Surya whose age is 7-years. Surya is playing by dipping balls in water tub. Dev observed that the level of the water increases when Surya starts dipping the balls one after the other in the water. Then Dev remembered his 6^(th) class topic measurement of volume. He poured water up to the brim of the tub and set up another bigger tub at the bottom of the first tub. He then asked his brother Surya to dip ten identical balls in it so that the overflowed water is collected in the tub at the bottom. Dev calculated volume of overflowed water and found that it was 2 litres. Dev calculated volume of each ball.Which of the following options matches with Dev's calculations?
