👉 Slabness is a property of an object or substance that indicates its degree of density, thickness, or rigidity. It refers to how much more dense an object is compared to another, and can be measured in terms of mass per unit volume (m^3/vol) or in terms of mass per cubic meter (m^3/m^3). Slabness is often used in the context of materials science to determine their strength, elasticity, and stiffness.
