Accepted Answer

Given, cuboid

The surface where a solid object stands on is called the base of the solid.

Base of a cuboid $=$ Rectangle

A face is any of the individual flat surfaces of a solid object.

Number of faces of a cuboid $= 6$

Edges are the lines at which faces meet.

Number of edges of a cuboid $= 12$

A vertex is the point at which when three or more edges meet.

Number of vertices of a cuboid $= 8$

Given, a cube

Base of a cube $=$ Square

Number of faces of a cube $= 6$

Number of edges of a cube $= 12$

Number of vertices of a cube $= 8$

A triangular prism:

A triangular prism has $5$ faces, $9$ edges and $6$ vertices.

A quadrilateral prism:

A quadrilateral prism has $6$ faces, $12$ edges and $8$ vertices.

A pentagonal prism:

A pentagonal prism has $7$ faces, $15$ edges and $10$ vertices.

A hexagonal prism:

A hexagonal prism has $8$ faces, $18$ edges and $12$ vertices.

A triangular pyramid:

A triangular pyramid has $4$ faces, $6$ edges and $4$ vertices.

A quadrilateral pyramid:

A quadrilateral pyramid has $5$ faces, $8$ edges and $5$ vertices.

A pentagonal pyramid:

A pentagonal pyramid has $6$ faces, $10$ edges and $6$ vertices.

A hexagonal pyramid:

A hexagonal pyramid has $7$ faces, $12$ edges and $7$ vertices.

Name of the Solid Base Number of faces Number of edges Number of vertices

Cuboid Rectangle $6$ $12$ $8$

Cube Square $6$ $12$ $8$
