Free practice on 3-D and 4-D Shapes for Class 3, following the Cameroon primary school curriculum (English subsystem). Every answer is explained, so a parent who is not sure of the answer can still help.
Flat shapes have length and width but no thickness. A piece of paper is flat! Triangles, squares, rectangles, and circles are all flat shapes.
Flat (2-D) shapes: Triangle · Square · Rectangle · Circle · Pentagon · Hexagon
Solid shapes have length, width, and height — you can hold them! A ball is a sphere. A box is a cuboid. A tin of milk is a cylinder.
| 3-D Shape | Looks like |
|---|---|
| Sphere | Football, orange |
| Cube | Dice, sugar cube |
| Cuboid | Shoe box, brick |
| Cylinder | Tin of milk, candle |
| Cone | Ice cream cone, funnel |
3-D shapes have faces (the flat surfaces), edges (where two faces meet), and vertices (corners). A cube has 6 faces, 12 edges, and 8 vertices.
| Shape | Faces | Edges | Vertices |
|---|---|---|---|
| Cube | 6 | 12 | 8 |
| Cuboid | 6 | 12 | 8 |
| Cylinder | 3 | 2 | 0 |
| Cone | 2 | 1 | 1 |
