3 D shapes have three dimensions length width

3 D shapes have three dimensions length, width and depth. When we talk about 3 D shapes, we talk about faces, edges and vertices. The faces are the flat parts of the shape. The edges are the lines where two faces meet. The vertices are the points where two or more edges meet. © hamilton-trust. org. uk 1 Year 3
