The tetrahedron has only four faces. A sphere has only one, but that's probably not what you meant since the surface of a sphere is curved.
triangle i guess
'Enneahedron' - a solid figure with nine faces
A solid figure with twenty faces is called an Icosahedron.
The Platonic solids, in order of number of faces, are:Tetrahedron - 4Cube - 6Octahedron - 8Dodecahedron - 12Icosahedron - 20Therefore, the fewest number of faces of a Platonic solid can be found on a tetrahedron.
were two or more faces of a solid figure
Hexahedron
Polygonal faces.
No.
A decaredra is the ten face solid figure.
NO!!!! A square is a two-dimensional shape, drawn on a surface. It has only one face, viz. the surface that it is drawn on. It has four sides, and four angles. A solid 3-dimensional figure with 6 congruent faces is a 'CUBE' . Each face of a cube is a 'square'. That is probably were you are confused!!!!!
