Area and volume describe how much space a shape covers or occupies — area for surfaces, volume for 3D objects.
Common Area Formulas:
Rectangle: A = l \times w
Triangle: A = \tfrac12 \, b \times h
Circle: A = \pi r^{2}
Common Volume Formulas:
Cube: V = l \times w \times h
Cuboid: V = l \times w \times h.
Cylinder: V = \pi r^2 h
Always use the correct units — cm² for area, cm³ for volume. Such skills are useful for design, building, or any measurement work.
