Sonar is the science of sending out sound waves to an object and waiting for them to be bounced back to a receptor.
Scientists can use this by shooting out the sound waves, then counting the amount of time it takes for the wave to shoot back to the receptor, and calculating the speed of the wave in proportion to the amount of distance traveled to get an idea of how large an object is.
They would need to do so on all sides of it, of course, and it probably helps that they have lots of equipment to help measure.
