How do I calculate a cross-sectional area?

Answer

To calculate a cross sectional area, you apply the same formula as for calculating the area of two-dimensional surfaces. The choice of formula depends on the shape. To find the area, you need a formula and relevant measurements. For example, to find the cross-sectional area of a box, the area is equal to (length X width).
