Question

10 kg petrol has density of 800 kg/m³. Find its volume in cm³.​

Answer 1

The answer is 12,500 cm³.

First, let's find the volume in m³.

Volume = Mass ÷ Density

• Volume = 10 kg ÷ 800 kg/m³

• Volume = 1.25 × 10⁻² m³

Now, to convert from m³ to cm³ :

m³ × 10⁶ = cm³

• 1.25 × 10⁻² × 10⁶
• 1.25 × 10⁴
• 12,500 cm³
