Question

We should drink 10 glasses of water in a day to stay fit. If one glass contains 210 ml of water, then we should drink _____ l to stay fit.

Answer 1

Quantity of water in one glass = 210 ml
Number of glasses = 10
Total quantity of water = $210\times 10=2100ml$

Also, $1ml=\frac{1}{1000}l$

$\therefore 2100ml=\frac{2100}{1000}l=2.1l$
