The volume of a cube or cuboid is length times width times height (L * W * H). So if you needed to calculate the density of a cube, you would first measure the length of one of the sides. Let's say that the length of our cube turned out to be 3 meters. You would first need to calculate the volume by multiplying 3 by 3 by 3 (V = 3 * 3 * 3). You would also need to put the cube on a scale to measure its mass. Last of all, you would divide your volume by your mass to get the density of the cube (p = m / v). Measuring the volume of a liquid isn't as obvious, because liquids change shape. When you measure liquids in a measuring jug, the numbers on the side are things like fluid ounces, pints, and liters (or milliliters). Liters are used in scientific equipment because those are standard scientific units. And there's a very good reason we use liters. Volume is measured in meters cubed, and 1 meter cubed is equal to 1,000 liters. So the conversion is super easy. (Also note that 1 liter is equal to 1,000 milliliters). Is this helpful?
