Answer 1

Given:

Increase in volume when water freezes = 10%

Measure of the side of a cubic container = 3 cm

To Find:

Volume of the ice cube when the water in cubic container freezes.

Solution:

Measure of the side of a cubic container = 3 cm

Volume of the cubic container full of water = (Side)³

                                                                        = 3³

                                                                       = 27 cm³

When water freezes into ice, increase in volume = 10%

Therefore, volume of the ice cube = 27 + (10% of 27)

                                                          = 27 + 2.7

                                                          = 29.7 cubic cm.
