A rather simplistic answer is: A cube or cuboid shape has (usually) 2 sides, 2 ends, 1 top and 1 bottom.
It is an octagonal prism
a right prism
it is a decogonanon it is a decogonanon
A cuboid is a 3D shape that can be a cube or a rectangle, both having 2 ends, 2 sides, and a top and a bottom face.
# of faces + # of edges + # of vertecies + 2
Yes, and three rectangular faces.
cylinder: 3 faces, 2 edges, no vertex
2D is a shape or an object that is flat and u can not pick it up, and it has 2 faces. 3D is a shape or an object that is a shape and you cant pick it up and hold it, and it can have as many faces.
A believe this is a cylinder (like the shape of a can), but there might be others.
.2d has 2 dimensions: corners and sides.3d has 3 dimensions: vortices (corners), sides and faces.
