No.
They might, but they do not have to. A very long and narrow parallelogram would have diagonals that cross at a very sharp angle.no they donot
Yes * * * * * Usually not.
It depends on the pyramid. If it is a square based pyramid, a horizontal plane will give a square cross section, a plane inclined by a rotation parallel to one of the base axes will give a rectangular cross section whereas a plane inclined by rotation along both basal axes will result in a parallelogram cross section. Not sure how you get a parallelogram from a pentagonal or hexagonal (etc) pyramid.
Volume of a parallelogram = cross-section area times length

Parallelogram
A parallelogram perhaps?
Formula for parallelogram prism is volume = cross sectional area times length. It can also be calculated by multiplying length, height and characteristic length.
The opposite sides of a parallelogram are parallel.The opposite sides of a parallelogram are equal.The opposite angles of a parallelogram are equal.The diagonals of a parallelogram bisect one other.The area, A, of a parallelogram is A = BH, where B is the base of the parallelogram and H is its height.The area of a parallelogram is twice the area of a triangle created by one of its diagonals.The area of a parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides.Each diagonal bisects the parallelogram into two congruent triangles.It is possible to create a tessellation of a plane with any parallelogram.The parallelogram is a special case of the trapezoid.The rectangle is a special case of the parallelogram.The rhombus is a special case of the parallelogram.
A parallelogram
yes a parallelogram is a parallelogram
find the area of the cross section then multiply by the other dimension (length, height, whatever you are calling it) Area of a parallelogram is base x height, area of a kite might need to be broken into triangles then added together.
