Detailed explanation-1: -The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre.
Detailed explanation-2: -“Density equals mass divided by volume.” Density is a compound measure which tells us about the mass of an object in relation to its volume. Density = mass ÷ volume = 500 ÷ 2.5 = 200 k g / m 3 .
Detailed explanation-3: -The formula for m in terms of d and V is m = d × V. The formula for the density of an object is d = m/V. where m is the mass and V is the volume.
Detailed explanation-4: -Therefore, density is dimensionally represented as [M1 L-3 T0].
