Frequently Asked Questions
When do I use area and when do I use perimeter?
Area measures the space inside a 2D shape (in sq.cm). Perimeter measures the distance around a shape (in cm). Perimeter is used for fencing; area for painting or flooring.
What is the difference between surface area and volume?
Surface area is the total area of all faces of a 3D object (in sq.cm). Volume is the space inside the 3D object (in cu.cm). Surface area for wrapping; volume for capacity.
