The volume (in dL) of the piece of iron having a mass of 3.92 kg is 4.99 dL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the volume of the iron</h3>
From the question given above, the following data were obtained:
- Mass of iron = 3.92 kg = 3.92 × 1000 = 3920 g
- Density of iron = 7.86 g/cm³
- Volume of iron =?
Density = mass / volume
Thus,
Volume = mass / density
Volume of iron = 3920 / 7.86
Volume of iron = 498.7277 cm³
Divide by 100 to express in dL
Volume of iron = 498.7277 / 100
Volume of iron = 4.99 dL
Thus, the volume of the iron is 4.99 dL
