# When 150 cm^3 of water freezes, 162 cm^3 of ice is formed. How do you calculate the percentage increase in the volume?

I got 8%

#### Explanation:

I would use fractions for % and volumes in the form:

$\text{total amount"/"increase}$

The volume increases of $162 - 150 = 12 c {m}^{3}$ so with fractions:

(100%)/(x%)=(150cm^3)/(12cm^3)

the percentual increase will be:

x%=100%*(12cancel(cm^3))/(150cancel(cm^3))=8%
