We all know that the volume of a cube with each side = 1

In fact, the volume of any higher dimensional hypercube
is also 1 because in any dimension n the volume = 1^n = 1.
Example, the volume of a hypercube of 100 dimensions is
1^100 = 1.
But what is the volume of a 100D hypersphere of radius = 1
that is inscribed within this 100D hypercube?

= 2.3682021018828293*10^-40
= 0.00000000000000000000000000000000000000023682021018828293
Why so fucking small, when the volume of the containing hypercube
is 1.0?
In fact, as the dimensions increase further, a hypersphere of radius=1
has a volume that approaches zero.
How can this be?
Consider a hypersphere of radius = 1 mile. As the dimensions increase
the volume will approach 0 cubic miles (i.e. nothing, zip, nada).
But the containing hypercube will always have a volume of 1 cubic mile.
Oblinux:
Maxima CAS was used to do the exact calculations.
Sounds like something one gets tempted to ask AI about it.
