This is usually considered to be the event horizon.
However a spinning black hole spinning fast enough or a charged black hole with high enough charge might not have an event horizon, leaving just what is called a naked singularity.
The boundary of a black hole is called the Event Horizon. It is, essentially, the point of no return.
Event Horizon.
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
There is no definite boundary for matter not being pulled toward a black hole. At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.
An event horizon is the boundary beyond which nothing, not even light, can escape the immense gravitational pull of a black hole.
The term black hole is a misnomer that implies the notion of a hole; there is no hole, so there is no hole foe light to escape into another multidimensional place. A black hole is a spherical volume of immense gravitational attraction. The interface presented towards the outside world, called the event horizon is not really a physical boundary: it's merely the point beyond which not even light can hope to escape the gravitational pull of the black hole.

Event Horizon.
The "boundary" you're probably thinking of is called the event horizon. Past this point, the escape velocity of the black hole exceeds the speed of light, meaning nothing, including light, can escape it.
By definition, the event horizon is a boundary of a black hole at which escape velocity reaches "c", the speed of light. Hence, the event horizon defines a boundary, within which, events can't affect an outside observer; neither light nor matter can escape.

At large distances the effects of a black hole's gravity are not different from that of a different object of the same mass. How far out a black hole's gravity is dominant depends on that black hole's mass and its proximity to other massive objects.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.

It's called the Event Horizon.
The object personally would disenigrate leaving only fair traces of it and that would be sucked up by the black hole on the edges because the center is the singularity or boundary.
The size of a black hole is a meaningless quantity. The black hole itself, meaning the matter contained within, is infinitely small. However black holes can be defined by their schwartzchild radius which is the size of the event horizon. Look the equation for it up somewhere.
The collapses star gets squeezed by collapses gas and turns into a black hole.
