To determine the weight of an object, the ______ must be calculated.

Weight is the gravitational force on an object, so it depends on the object's mass. To determine weight, you need the mass. You can get mass directly with a scale, or compute it from density and volume since mass = density × volume. Once you have mass, multiply by the local gravitational acceleration (weight = mass × g) to get the weight. Volume alone can’t determine weight because different materials with the same volume can have different masses due to varying densities. Area isn’t involved in the weight calculation. So, the essential quantity to determine weight is mass.
