This is a question relating to the scientific concept of density. Density is defined as the mass per unit volume of a substance, and it's usually represented with the Greek letter ρ (rho). Thus, ρ = m/V, where "m" represents the mass of the substance and "V" its volume. In this question, we are given the density (massa jenis) as 790 kg/m³ and the volume (volumenya) as 24,000 cm³. Taking into account that 1 m³ equals 1,000,000 cm³, we must first convert the 24,000 cm³ into m³ by dividing by 1,000,000. Given that estimating the mass is consequent upon multiplying the volume (in m³) by the density (in kg/m³), solving for mass ("m") entails substituting these known values (density and volume) into the formula aforementioned in the order of taking their product. Once this is computed, We can compare the result to the given answer choices.
