Understanding the question:

  • We are asked to calculate the mass of the object whose density is 3 kg/m³ and volume is 15 m³

Provided that:

  • Density = 3 kg/m³
  • Volume = 15 m³

To calculate:

  • Mass

Solution:

  • Mass = 45 kg

Using concept:

  • Density formula

Using formula:

  • D = m/v

Where, D denotes density, m denotes mass and v denotes volume.

Required solution:

»»» Density = Mass/Volume

»»» D = m/v

»»» 3 = m/15

»»» 3 × 15 = m

»»» 45 kg = m

»»» m = 45 kg

»»» Mass = 45 kg

  • Henceforth, the mass of the object is 45 kilograms.

Additional information:

\begin{gathered}\boxed{\begin{array}{c}\\ {\pmb{\sf{Some \: formulas!}}} \\ \\ \sf \star \: Density \: = \dfrac{Mass}{Volume} \\ \\ \sf \star \: Volume \: = \dfrac{Mass}{Density} \\ \\ \sf \star \: Density \times Volume = Mass \end{array}}\end{gathered}

Density: Density is defined as the mass per unit volume. Density is depend on the property that how tightly the particles are packed in a substance.

The SI unit of density = kg/m³

The CGS unit of density = g/cm³

Have you ever listen about relative density!? What is it!?

Relative density is defined as the density of substance per density of water.
