Question

When water freezes its volume increas es by 4%.what volume of water is required to make 221cm

Answer 1

Answer:

212.5 cm^3

Step-by-step explanation:

lets take volume of water as 'x'

x + 4/100 x = 104/100 x

104/100 x = volume of ice

therefore, 104/100 x = 221cm ^3

104/100 x = 221cm ^3

x = 221 × 100/104 cm^3

x = 212.5 cm^3 (volume of water)

Answer 2

Let x be the volume of water.

=>x + 4/100x = 104x/100 volume of ice
104x/100 =221cm³

=>x = 221 * 100/104cm³
x = 212.5cm²
