To find out how many small rocks are needed to equal the mass of the larger rock, we first convert the mass of the larger rock from kilograms to grams: 3 kilograms = 3000 grams. Since each small rock weighs 2 grams, to find the number of small rocks needed, we divide the mass of the larger rock by the weight of each small rock: 3000 grams / 2 grams per small rock = 1500 small rocks. Therefore, it would take 1500 small rocks to equal the mass of the larger rock weighing 3 kilograms.
