A student is determining the density of an irregularly shaped piece of basalt. Which equation should the student use to calculate the density of this solid?
density=volumemass\text{density} = \frac{\text{volume}}{\text{mass}}density=massvolume
density=mass×volume\text{density} = \text{mass} \times \text{volume}density=mass×volume
density=massvolume\text{density} = \frac{\text{mass}}{\text{volume}}density=volumemass
density=mass−volume\text{density} = \text{mass} - \text{volume}density=mass−volume
