Question

when water freezes its volume increases by 4% what volume of water is required to make 221 cube cm

Answer 1

Let,
x volume of water is required to make ice cube.
volume increases by 4% after freezing.
So, x * 104% = 221
or, x = (221*100)/104
or, x = 22100/104
or, x = 212.5 cubic cm

Answer 2

Answer:

221.5

Step-by-step explanation:

Let volume of water be x.

Ice cube required= 221

Volume after freezing= x X 104% = 221

= x X 104/ 100 = 221

= x = (221 X 100) / 104

= x= 212.5

So, 212.5 cm^3 volume if water is required to make 221 cm^3 of ice.
