All 12 sides are straight! This is a 2 dimensional object. * * * * * A dodecahedron is NOT a 2 dimensional object so the above answer is utter nonsense. A dodecahedron has pentagonal faces.
rectangular prism.It has 6 faces and 12 edges. The 2 bases are congruent to each other, and the remaining 4 faces are congruent to each other, but the bases are not necessarily congruent to the other faces.
A tetrahedron (or triangular pyramid).
A cube. Or a triangular bipyramid.
an octagon * * * * * An octagon has 8 sides. An object with 8 faces is an octahedron.
A cube has 6 faces. A square has 2 faces if it is only a flat object.
