The kilogramme.
The mass of the dog will be 56kg.
mass of a substance or an object
You would use the unit of measure called "kilograms" to measure the mass of an elephant.
The mass of the dog can be calculated by setting up an equation. If we let x be the mass of the dog, then the equation would be x = 10 + 0.5x. Solving this equation, we find that the mass of the dog is 20 kilograms.
If the dog does not stand on the scale, the scale will only measure the mass of whatever is placed on it besides the dog. So whatever object is placed on the scale will be the mass that is measured, not the mass of the dog.
Milligram: to measure its mass.
No, millilitres is a measure of volume not mass. You would use milligrams.
The most common thing you would measure mass in would be grams and kilograms
