If “hole” can be defined purely as an opening, then perhaps a straw does have two holes. If a hole is defined mathematically, like a torus shape, then a
straw has one hole
.
How many holes does a hollow cylinder have?
It is a hollow cylinder with
2 openings at either end
. However if we flattened it into a disc, there would only be one area that is completely “punched out”, which means one hole by this definition.
Does cylinder have one or two holes?
Two openings, one cavity

Does a paper towel roll have one hole or two?
One Hole: The argument for the answer “one hole” is that a roll of paper towels (or toilet paper, straw, etc.) is that the object has one opening through the middle of it. That one opening is the one hole the object has.
Two Holes

How many holes does a pair of pants have?
A pair of pants is any surface that is homeomorphic to a sphere with
three holes
, which formally is the result of removing from the sphere three open disks with pairwise disjoint closures.
Does a hole have to have an end?
A
hole needs two ends to be a
hole…” “It has one. Imagine trying to make it have fewer; If you plugged the hole it would have none.”
How many holes has a straw got?
For a surface with boundary, such as a straw with its two boundary circles, each cut must begin and end on a boundary. So, according to Riemann, because a straw can be cut only once — from end to end — it has exactly

has no holes
. It is a pipe. If it had a hole, it would leak.” “‘Technically’ a straw has one hole but ‘technically’ it does not.
How many holes does a donut have?
Topologically, that would be the same as S1 × D, where D is a disc (imagine gluing a disc to each point around a circle). This is actually true since the disc can be deformed to an interval–just squash it to a diameter. The assertion is then that a donut “clearly” has
one hole
.
