Question

what is the minimum number of faces required to form a solid​

Answer 1

Answer:

6 faces are required to form a solid of shape of cube or cuboid

Answer 2

Answer:

A solid can be formed even without a face. Eg : Sphere have no faces only a curved surface

Step-by-step explanation:

A solid is a figure or shape that has 3 (or more) dimensions

It should have a volume along with the surface area

And faces is a flat surface that forms the boundary of the solid

Here, let us take some examples

A sphere has no faces but has a curved surface area

For a sphere, a face is a flat surface and should be a part of a plane , so the curved surface of sphere is not a face

Also, if we consider sphere has infinite faces according to Euler's formula , then it has no area

So, we can conclude that a sphere has no faces

A cone has 1 face and a curved surface

A cylinder has 2 faces and a curved surface area

A triangular pyramid has 4 faces

A square pyramid has 5 faces

A cube has 6 faces

Here, sphere is a solid shape but it does not have any faces.

So even with a zero face, a solid can be formed

So, a solid can be formed even without a face
