3 dimensional shapes nets2/27/2024 Nets can also be described as an unfolded 3D-figure. Here, a 2D-shape can be folded in a specific way to form a 3D-shape. The shapes and the properties of the three-dimensional shapes can be well understood by using nets. Here is a table of different 3D shapes and their formulae. On the other hand, volume refers to the amount of space a 3D-structure occupies. The surface area refers to the area covered by a 3D-structure at the bottom, top and all the faces including the curved surfaces.

It has identical polygonal ends and flat faces It has the same cross-section along the length. Based on the apex alignment they can be classified into regular and oblique pyramids. It is a polyhedron with a polygon base and an apex with straight lines. It has six faces, each of them is rectangular in shape. There are six faces, each in the shape of a square All sides are of equal length Total number of diagonals is 12. It has one pointed vertex at the top and a flat base. The bases are parallel and congruent It has one curved side. All the points on the surface are equidistant from the center. The following is a table of some of the 3D shapes with their properties.
