yes at least 1 face
2d shapes only have length and width, while 3d shapes have length, width and depth.
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons.
Only one; a triangle is a 2D shape, not a 3D shape. Usually only 3D (or more) shapes are considered to have 'faces'.
A dodecahedron is a polyhedron with between 18 and 30 faces.
A net is a 2D representation of a 3D shape
1. both of them have hight and width
yes at least 1 face
a 2d shape can only ever contain 1 face!
Give vidoes to understand the 2d and 3d shapes clearly
2d shapes only have length and width, while 3d shapes have length, width and depth.
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
I think they all have 1.... because 2d shapes are flat!!! :)
The difference between 2d and 3d shapes is that, a 2d shape is flat, has no volume and depth and cannot be handled while a 3d shape can be held, has depth, volume and can hold things inside it. These are the dimensional shapes which are mostly used in geometry.
