How people figure out this formula?

Vn is Volume of n-dimensional pyramid.
Vn = A∙h/n

A is the area of the base, and I think they integrate it along the height. I'm not sure why they divide by the dimension. I could not find a derivation of that formula.

I found a formula for regular hyperpyramids: Vn = rn/n

r is both the edge length and height.

They work out that formula here: http://www.physicsinsights.org/pyramids-1.html

An n-pyramid, or n dimensional hyperpyramid, is analogous to a triangle in arbitrary dimensions. It's formed by starting with an (n-1)-cube, and sweeping the cube perpendicular to itself, just as we did in forming an n cube (see hypercubes for a discussion of n-cubes and their volumes).
Question:
(1) Why the sentence in the beginning start with An?
(2) What is sweeping?
