The density of sand is `1500 "kg/m"^3`. What is the mass of `1m^3` of sand ?

Answer

To find the mass of 1 cubic meter of sand given its density, we can follow these steps:

### Step 1: Understand the relationship between density, mass, and volume.
The formula that relates density (D), mass (M), and volume (V) is:
\[ D = \frac{M}{V} \]
Where:
- \( D \) = Density (in kg/m³)
- \( M \) = Mass (in kg)
- \( V \) = Volume (in m³)

### Step 2: Rearrange the formula to find mass.
To find the mass, we can rearrange the formula:
\[ M = D \times V \]

### Step 3: Substitute the known values into the formula.
We know the density of sand is \( 1500 \, \text{kg/m}^3 \) and the volume we are considering is \( 1 \, \text{m}^3 \). Substituting these values into the formula gives:
\[ M = 1500 \, \text{kg/m}^3 \times 1 \, \text{m}^3 \]

### Step 4: Calculate the mass.
Now we can perform the multiplication:
\[ M = 1500 \, \text{kg} \]

### Final Answer:
The mass of \( 1 \, \text{m}^3 \) of sand is \( 1500 \, \text{kg} \).
