if we have a value in cm3 nominator and denominator in cm how to get the value in cm2. sound silly .pls help me out
+122 If you divide a volume in cm^3 by cm the number you get will be in cm^2.
Here's why: Let's take 1000cm^3/100cm for example
Numerator is really (10xcm)x(10Xcm)x(10xcm) =(10x10x10)x(cmxcmxcm)
Denomitor is 100xcm
the dimensions ,that is the cm,cancel down just as the numbers do,so the cm on the denominator cancels out one cm on the numerator,leaving you with the answer 10cm^2.
Similarly,if you divided a volume in cm^3 by cm^2,your answer would be in cm. The thing to realise here is that you mutiply and cancel dimensions just as you do with numbers.
