Dani wants to measure the volume of a pebble. Which tool will give the most accurate measurement

The answer is graduated cylinder.

Dani requires a graduated cylinder to measure the volume of the pebbles. A graduated cylinder is actually laboratory equipment to measure the volume of a liquid. Dani must place a specific amount of liquid in the cylinder and record the amount. Dani will then put the pebbles inside the cylinder and subtract the amount of liquid previously recorded to the current amount to get the volume of the pebbles.
