Estimating human volume via mass and density

Steps:

• Average adult mass is about 70 kg.
• Human body density is approximately 1000 kg/m³, similar to water.
• Calculate volume using V = m / ρ = 70 kg / 1000 kg/m³ = 0.07 m³.
• Round to nearest option: 0.1 m³.

Why A is correct:

• Volume formula V = m / ρ yields 0.07 m³ for typical adult mass and water-like density, closest to 0.1 m³.

Why the others are wrong:

• B: 0.5 m³ implies 500 kg mass, far exceeding human weight.
• C: 1 m³ implies 1000 kg mass, impossible for a person.
• D: 2 m³ implies 2000 kg mass, absurdly large.

Final answer: A
