- 3. Solid Shapes A solid shape is a shape which has a defined length, breadth and width. It is also known as a 3-Dimensional or 3-D shape. An easy way to think of a 3D shape is any shape or object that takes up air space. They have 3 main components- (1) Face (2) Edge (3)Vertex Face Edge Vertex
- 4. Cube Faces: 6 Edges: 12 Vertices: 8 2D equivalent: Square Examples: Dice, ice cube, Rubik’s cube Rubik’s Cube Ice Cube Dice Net of a cube A Cube A Square
- 5. Cuboid Face: 6 Edges: 12 Vertices: 8 2D equivalent: Rectangle Examples: Eraser, doors, books Eraser Books Door Net of a cuboid A Rectangle A Square
- 6. Sphere Faces: 1 Edges: 0 Vertices: 0 2D equivalent: Circle Examples: Earth, football, marbles A Sphere A Circle Net of a sphere Football Earth Marbles
- 7. Cone Faces: 2 Edges: 1 Vertices: 1 2D equivalent: Triangle (approx.) Examples: Ice cream & road cones, party hats Net of a cone A Triangle Ice cream cone Party hat Road cone A Cone
- 8. Cylinder Faces: 3 Edges: 2 Vertices: 0 2D equivalent: Circle (approx.) Examples: Dry cells, watering cans, mugs A Cylinder A Circle Net of a cylinder Watering can Dry cell Mug
- 9. Pyramid Faces: 5 or 4 Edges: 8 or 7 Vertices: 5 or 4 2D equivalent: Triangle (approx.) Examples: Giza pyramids, conundrum, paperweights A Square Pyramid Net of pyramids Paperweight Giza pyramids Conundrum A Triangular Pyramid
- 10. Prism Faces: 5 Edges: 9 Vertices: 6 2D equivalent: Rectangle Examples: Rooftop, ‘Toblerone’, cheese A Rectangle A Prism Net of prism Toblerone CheeseRooftop
- 11. View of an Object from Varying Points Any 3D object can look differently from varying point and so can be drawn from different perspectives. A solid can have 3views, these are: 1. Top view 2. Side view 3. Front view
- 12. Mapping Areas Around UsWhat is a Map? A map is a 2D drawing made according to a specific scale. It depicts the location of an object with respect to its surroundings. While making maps, one must keep the following things in mind: ~Use certain symbols to represent specific places; these are also known the legend. ~Maintain a proper scale
