(a) What are the universally accepted basic metric units?(b) A cow gives 10 litres of milk in the morning and 8 litres in the evening. Find the total milk it gives for a week in ml?

Answer»

(a) Universally accepted basic metric units are:
Length in metre, Weight in gram and Capacity (Volume) in litre.

(b) Litres of milk the cow gives in the morning = 10 l.

Litres of milk the cow gives in the evening = 8 l.

Total milk per day = 10 + 8 = 18 l

Total milk for a week = 18 × 7 l = 126 l = 126 × 1000 ml = 126000 ml.

Total milk the cow gives for a week = 1,26,000 ml.
