We should drink at least 10 glasses of water in a day to stay fit. If one glass contains 210 ml of water, then 10 such glasses amount to _____ mL of water.
2100
Capacity of one glass = 210 mL
Number of glasses = 10
∴ Total quantity of water
= 10 × 210 mL = 2100 mL
Thus, 10 glasses of water amounts to 2100 mL of water.
