What is the cross-sectional area?
The cross-sectional area of a cuboid The volume of any cuboid (including cubes) is Base area (length times width) times height: V = l × w × h. Therefore, if the cross section is parallel to the top or bottom of the solid, the area of the cross section is l × w.
What is an example of a cross-sectional area?
Cross-sectional area is the area of a two-dimensional shape, obtained when a three-dimensional object (such as a cylinder) is sliced at a point perpendicular to a specified axis. …for example, the cross-section of a cylinder – when sliced parallel to its base – is a circle.
What is the difference between area and cross-sectional area?
Area is the area that an object occupies when it rests on a surface, i.e. area is the space used by the object.while the cross-sectional area is The area we get when the same object is cut into two pieces.
What is the surface area formula?
