It is use full because they can all be map on to different members
When cross multiplying, finding the product of the means and extremes, you are technically getting a common denominator that reduces out.
The surface gauge is useful when finding the center of a cross-sectional piece of a round section.
Because in both cases their diagonals cross at right angles So their areas are: 0.5*product of diagonals
I think you meant to ask for finding a perpendicular vector, rather than parallel. If that is the case, the cross product of two non-parallel vectors will produce a vector which is perpendicular to both of them, unless they are parallel, which the cross product = 0. (a zero vector)

0 is a cross product of a vector itself
The cross section is useful as it cuts across any type of shape. This is useful for architects who will be able to see the finer details of a structure.

The cross product can be said to be a measure of the 'perpendicularity' of the vectors in the product. Please see the link.
Normally you use sine theta with the cross product and cos theta with the vector product, so that the cross product of parallel vectors is zero while the dot product of vectors at right angles is zero.
because that is the def. of a cross-product!
Cross sections are useful because it shows what the sightseers cant see, the landforms beneath the land surface.
