How much formwork is required for footings formed along the sides?

To determine the amount of formwork required for footings formed along the sides, it's essential to understand that formwork is used to create molds for concrete to set in until it hardens. The calculation typically involves measuring the perimeter of the footing and the height at which the concrete will be poured.

If the answer indicates that 224 square feet of formwork is necessary, this suggests a footing that requires extensive coverage based on its perimeter and depth. For instance, if the footings are sufficiently wide and deep, requiring substantial side formwork on all sides, this sum would reflect that requirement.

The context or dimensions of the footings (length, width, and height) would usually provide a clearer picture of how the value of 224 square feet comes into play. This answer implies that the combined height and perimeter measurements lead to this total area of formwork, which might be calculated as:

1. Perimeter calculation: Adding up the lengths of all sides of the footing.

2. Depth of formwork: Multiplying the perimeter length by the height of the footing (if you are forming both sides).

Thus, with careful consideration of the dimensions involved, 224 square feet represents a calculated requirement based on the necessary coverage to adequately
