Cross sectional area formula for rectangle. To calculate the cross sectional area of a plane through a three dimensional solid you need to know the precise geometry of the solid and the angle the cutting plane makes with the solids axis of symmetry if any. Learn how to calculate the area of a square and rectangle. Whereas cross sectional area is an area which we obtain when the same object is cut into two pieces.
Cross sectional area can also be width and height the terms length width and height are somewhat generic. In geometry and science a cross section is the non empty intersection of a solid body in three dimensional space with a plane or the analog in higher dimensional spacescutting an object into slices creates many parallel cross sections. The same applies for the tensile area too.

Area is somewhat that is occupied by an object when it is resting on a surface ie area is the space which is used by the object. The area of that perticular cross section is know as cross sectional area.
The area of cross sections have unique formulas depending on the solid. For the case of a rectangular cross section the plastic neutral axis passes through centroid dividing the whole area into two equal parts. For example lets say one side of the building is eight feet long and the other side is six feet long.
Surface area is its analog on the two dimensional surface of a three dimensional objectarea can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape or the amount of paint necessary to cover the surface with a.
