That one opening is the one hole the object has. Two Holes: This explanation makes more sense with things like rolls of paper towels/toilet paper.
Does a straw have no holes?
“It has one hole, because it’s topologically equivalent to a doughnut and a coffee cup (and some would say a human, though we’re arguably more of a genus-5).” “One hole, it’s topologically alike to a donut. And, fun fact: a human.
How much holes does a girl have?
There are two openings in the vulva — the vaginal opening and the opening to the urethra (the hole you pee out of). The urethral opening is the tiny hole that you pee out of, located just below your clitoris. The vaginal opening is right below your urethral opening.

A hole in a mathematical object is a topological structure which prevents the object from being continuously shrunk to a point. When dealing with topological spaces, a disconnectivity is interpreted as a hole in the space. … There are many ways to measure holes in a space.
What is a straw used for?
Straw…it’s more than just the leftover from wheat harvest. This agricultural byproduct has a huge number of uses. While some are quite traditional like the bedding for animals and mulch in the garden, it can also be used as a quality cattle forage, heating fuel, ethanol production, or even as a building material.

How many holes does a pair of pants have?
three holesPants and pants decomposition As said in the lede, a pair of pants is any surface which is homeomorphic to a sphere with three holes, which formally are three open disks with pairwise disjoint closures removed from the sphere. Thus a pair of pants is a compact surface of genus zero with three boundary components.
Is using a straw better for your teeth?
Drinking through a straw can minimise tooth contact, giving you healthier and happier teeth. Using a straw will also allow you to consume beverages that are known to cause stain with less direct contact on teeth. This will reduce tooth discolouration.

18 holesWell, near the beginning it had 18 holes, that is. And eventually, other courses were copycats. Those are the broad strokes of how a typical golf course came to have 18 holes.
What makes a hole a hole?
A hole is an opening in or through a particular medium, usually a solid body. … Depending on the material and the placement, a hole may be an indentation in a surface (such as a hole in the ground), or may pass completely through that surface (such as a hole created by a hole puncher in a piece of paper).
