![]() ![]() Unlike two-dimensional figures, 3D shapes have thickness or depth.3D shapes are those objects or solids having three dimensions- length, width and height.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 the same cross-section along the length.It has identical polygonal ends and flat faces.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.It has one pointed vertex at the top and a flat base. ![]() 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. Here is the table showing the faces, edges and vertices of 3D shapes.It is the point where two or more edges meet.It serves as the junction of two faces.An edge refers to the line segment on the boundary joining the adjacent vertex.There can be more than one shape in a 3D object.It refers to any single flat or curved surface of a solid shape.They are broadly classified into regular prisms and oblique prisms.ĭue to the presence of three dimensions- length, breadth and height, 3D shapes have faces, edges and vertices.It has the same cross-section all along with the shape.Prisms are solid three-dimensional shapes with identical polygon ends and flat parallelogram sides. A pyramid with a regular hexagon as its base is called a hexagonal pyramid.A pyramid with the base of a pentagon is named a pentagonal pyramid.A pyramid with a quadrilateral base is termed a Square pyramid.A pyramid with a triangular base is called a Triangular pyramid.Based on the alignment with the center of the base, they can be classified into regular and oblique pyramids.

The length, width and height of a cube are always the same while for a cuboid they are different. They have different volumes and have different surface areas. The main difference between the two objects is that all the six faces of a cube are squares whereas the faces of the cuboid are rectangles. The following are the common polyhedrons- Cube and CuboidsĬube and cuboid are three-dimensional shapes having the same number of faces, vertices and edges. ![]() The fundamental properties of polyhedrons are. Polyhedrons are 3D-shapes having straight sides. The one in which the base is placed away from another is called an oblique cylinder. A cylinder having both circular bases lying on the same line is called a right cylinder.It has two identical ends that are either circular or oval.Here are some important characteristics of a cylinder. The height is the perpendicular distance between the top and the bottom faces. Thus, a cylinder has a radius and height. Read Also: Surface Area of Rectangular Prism CylinderĪ Cylinder can be described as a 3D-shape having two circular faces, one at the bottom and one at the top, and a curved surface. Apart from that it also has a slant height which is measured as the distance between apex and any point on the circumference of the circular base of the cone. ![]() If the apex lies anywhere away from the center of the base it is called an oblique cone.
