A stone has a mass of 15 kg and a volume of 0.4 m³. What is its density?

Question

ScanSolve AI Tutor · Accepted Answer

The question has a typo: "its mass is 0m³" should refer to the volume of the stone. Given the multiple-choice options, we will assume the intended volume was 0.4 m³ to match one of the answers.

Identify the given mass and assumed volume.
The mass of the stone ( $m$ ) is given as 15 kg.
We assume the volume ( $V$ ) is 0.4 m³ to align with the provided options.
State the formula for density.
Density ( $\rho$ ) is calculated by dividing mass by volume.
$\rho = \frac{m}{V}$
Substitute the values into the formula and calculate the density.
$\rho = \frac{15 \text{ kg}}{0.4 \text{ m}^3}$ $\rho = 37.5 \text{ kg/m}^3$
The calculated density matches option A.

The density of the stone is $\text{A. 37.5 kg/m}^3$ .
