Amit has found a rock in his backyard and would like to measure its mass, volume, and density. what tools can he use to perform these measurements? meter stick, balance, and graduated cylinder graduated cylinder and balance meter stick and balance graduated cylinder and meter stick

a graduated cylinder and balance

A rock has an irregular shape. so, it would be difficult to measure using a meter stick. most convenient method to find the volume would be using a graduated cylinder. we can take a fixed volume of water in the cylinder. then drop rock into it. note the new raised volume. Subtract the initial volume from final to find the volume of rock.

Using balance, mass of the rock can be measured.

we can calculate the density using the following formula:

Therefore, we need only two tools, a graduated cylinder and a balance to measure mass, volume and density of a rock.
