Three Dimensional Geometry: Explanation, Formulae and Practice

Three-dimensional geometry studies solid shapes such as cubes, cuboids, cylinders and cones. For school revision, focus on identifying the shape, writing the correct dimensions, choosing the right formula, and keeping units consistent.

Practical Formulae

  • Cuboid volume = length x breadth x height.
  • Cuboid total surface area = 2(lb + bh + hl).
  • Cube volume = side x side x side.
  • Cube total surface area = 6 x side x side.
  • Space diagonal of a cuboid = sqrt(l^2 + b^2 + h^2).
  • Space diagonal of a cube = side x sqrt(3).

Solved Example

Question: A cuboid has length 8 cm, breadth 5 cm and height 3 cm. Find its volume.

Working: Volume = l x b x h = 8 x 5 x 3.

Result: Volume = 120 cubic cm.
