Black holes are most often discussed in terms of their mass, but how much volume do these hefty, invisible objects actually have?
Lurking at the center of the Milky Way is a gargantuan black hole that tips the scales at several million times the mass of the Sun. Like all black holes, this supermassive monster — called Sagittarius A* — devours anything that falls too close, including light. However, consuming material is just one way these monsters grow to truly astronomical sizes, reaching mindboggling weights. Although astronomers often talk about black holes as being gigantic objects, it’s important to remember they’re usually referring to the object’s mass, not its physical size.
So, one obvious question is: How much space do different types of black holes take up?
Black hole weight classes
The standard black hole, known as a stellar-mass black hole, forms when a massive star (greater than about 8 solar masses) reaches the end of its life. After depleting the last of its remaining nuclear fuel, the star’s uncontested gravity causes it to rapidly collapse before rebounding outward in an epic blast known as a supernova. What remains, depending on the mass of the star, will either be a neutron star or a black hole. These stellar-mass black holes can range from a couple to several dozen times the mass of the Sun.
However, the origins of supermassive black holes like Sagittarius A*, which can range from millions to billions of times the mass of the Sun, remain unknown. Astronomers do know their extreme size and mass seems to be related to the galaxies they call home, with the biggest supermassive black holes found in the centers of the biggest galaxies.

Earth, Wind, and Fire is my guess.
The only essential elements missing in that pic are Zappa, Who, and Rush. I will accept Hendrix or a good punk band like the Dead Kennedy as substitute isotopes.
Definitely not ELO.
At the center of a black hole is believed to be an infinite gravitational well in the fabric of spacetime, called a gravitational singularity.
Nothing is infinite in the real universe. While infinities are common in the abstract universe of math, they just indicate failure points where the math models cease approximating the real world.

Depends on the size of the peg.
Hilarious article. Works kind of like this:
1. Ask how large black holes are
2. Provide lots of background information about everything other than volume
3. Go to 1.
To find the answer to the question I searched on the word miles, and found it in the 13th and 15th paragraph. (one is 10 and one is 578 miles in diameter). Then you get another size measurement for progressively larger black holes every two or three paragraphs afterwards.
No kidding, or STYX.
As much as it wants.

Technically, if they actually existed, none. If you’re counting the event horizon, that varies.
Mass, size, weight, volume...
Just pick one at random, as needed, and throw it in the article. No worries.
African or European black hole?
So, if eventually all the universe collapses and becomes black holes, say there is for some reason then a reaction, an explosion of these black holes and then = stars,, planets...a universe is created.
The Big Bang..again?
Density is mass divided by volume. If the density of a black hole is infinite, the volume must be zero.
The movie “Interstellar” is great. They spend a brief interval on a planet just outside the event horizon, and find 22 years have elapsed on the orbiting craft that launched their probe.
An astronomy book my older brother had turned me into a space nerd before I was 10. I got dizzy reading a passage about the limitlessness of space, and the temperature of stars as “trillions of degrees”. That hooked me.
called Sagittarius A* —
Tell me the A* is not a-hole....
