This question is a bit of a trick! Buoyancy is determined by the volume of an object, not its shape.

Here's why:

* Buoyancy: The upward force exerted on an object submerged in a fluid (like water).

* Volume: The amount of space an object takes up.

To answer your question:

If you have a round, square, and triangle object that all have the same volume, they will all be equally buoyant.
