Question

Select the most reasonable metric unit for a glass containing 400 units of liquid. Choose from​ L, mL,​ kg, g, and mg.

Answer 1

ml

Explanation:

This is one of those questions where you wish the author had asked for the best 2.

A glass is normally measured in mL unless it is awfully big, in which case it would be measured in liters.

The water itself is most accurately measured in grams or mg.

So what to do.

I think the question intends you to answer mL because it is asking about the glass.
