Question

Researchers randomly assigned participants either a tall, thin "highball" glass or a short, wide "tumbler," each of which held 355 ml. participants were asked to pour a shot (1.5 oz = 44.3 ml) into their glass. did the shape of the glass make a difference in how much liquid

Answer 1

The shape of the glass will not affect how much it can hold, as they both hold 355 ml.  What it will affect is the height of the liquid in the glass.
