Cube:

A cube is a 3-D solid shape, which has 6 sides. Along with that, it has 8 vertices and 12 edges such that 3 edges meet at one vertex point.

Cuboid:

A cuboid is a polyhedron having six faces, eight vertices and twelve edges.

Cone:

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base to a point called the apex or vertex.

A number of edges zero, the number of vertices is zero and the number of the face is 1.

Cylinder:

A cylinder is one of the basic shapes, in Mathematics, which has two parallel circular bases at a distance. LPG gas-cylinder is one of the real-life examples.

A number of edges zero, the number of vertices is zero and the number of the faces is 2.

Sphere:

A sphere is an object that is an absolutely round geometrical shape in three-dimensional space.

A number of edges zero, the number of vertices is zero and the number of the faces is zero.

Triangular pyramid:

When you observe the shape of the Great Pyramid of Egypt, then you will notice that the pyramid has a base, that is square-shaped. Hence, those pyramids are called Square Pyramid. Similarly, in the triangular pyramid, the base of the same is triangular.

A number of edges six, the number of vertices is four and the number of the faces is four.

Rectangular prism:

A rectangular prism is a 3D shape. It has six faces, and all the faces of the prism are rectangles. Both the bases of a rectangular prism must be a rectangle. Also, the other lateral faces will be rectangles. It looks like cuboid.

A number of edges twelve, the number of vertices is eight and the number of rectangular faces is six.
