Question

choose the correct answer. which two variables are used to find the density of a substance? mass and volume length and width

Explanation:

The formula for density is \(
ho=\frac{m}{V} \), where \(
ho \) is density, \( m \) is mass, and \( V \) is volume. Length and width are used to calculate area (for 2 - D shapes) or can be part of calculating volume (for 3 - D shapes if height is also known), but they are not directly the variables in the density formula. Mass and volume are the two variables specifically in the density formula.

Answer:

mass and volume
