Hello!
To find the density of any material or object, we would need to use the formula: d = m/V.
The formula d = m/V is saying: density is equal to mass divided by volume.
We are given the mass, which is 79 grams, and the volume, which is 15 cm³. With those values, we can find the density by dividing.
79 grams / 15 cm³ = 5.3 grams/cm³
Therefore, the density of the material is about 5.3 grams/cm³.
