I'm trying to determine the calculation which would state the upward force of a container where the density inside the container is less then that in which it sits.
Does this calculation change with shape? I.e. sphere vs cube?

The resultant upward force= upthrust-weight
Thus, the formula for the volume will change according to the shape of the container
2.weight=density inside container*volume of container*9.81
If the upthrust is more than the weight of the object, the object moves upwards
