3D Shapes

On a 3D shape, flat surfaces are called faces, the lines where two surfaces meet are called edges and the corners where two edges meet are called vertices. Edges can be curved or straight.

  • A cuboid has 6 faces which are all rectangles. It has 12 edges and 8 vertices. Its edges are not necessarily all the same length.

  • A cube is a special kind of cuboid whose edges are all the same length so that its 6 faces are identical and all squares.

  • A prism is a 3D shape with flat faces and an identical cross-section throughout the length of the shape.
  • A prism has two end faces called bases then one face for each side of the base.

  • This is a square based pyramid.
    • Square based pyramids have 5 faces, 5 vertices and 8 edges.
    • Triangular based pyramids have 4 faces, 4 vertices and 6 edges.
Illustrative background for CylinderIllustrative background for Cylinder ?? "content


  • A cylinder has a flat face at each end called a base, and a curved surface along its length.
  • It has two edges (one around each base) and no vertices.

  • A cone has 2 surfaces, 1 edge and 1 vertex.
  • The top of a cone is called the apex.
