How do you calculate the sq ft of 3 dimensional object? - Answers

To calculate the square footage of a three-dimensional object, you typically need to find the surface area rather than just square footage, as square footage refers to a two-dimensional measurement. For regular shapes, you can use specific formulas: for example, the surface area of a cube is 6 times the area of one face (6 * side^2), while the surface area of a rectangular prism is 2(lw + lh + wh). For irregular shapes, you may need to break the object down into smaller, regular shapes, calculate their surface areas, and then sum them up. Remember that the units will be in square feet (sq ft) as long as the dimensions are in feet.
