What is the density of a 700 kg object with a volume of 649 m3? (Density: D = D = m over v.)

0.927 kg/m3
.4543 kg/m3
1.079 kg/m3
4.543 kg/m3

1 answer

To find the density (D) of an object, you can use the formula:

\[ D = \frac{m}{v} \]

where:

  • \( m \) is the mass of the object,
  • \( v \) is the volume of the object.

Given:

  • Mass \( m = 700 \) kg
  • Volume \( v = 649 \) m³

Now, substitute the values into the formula:

\[ D = \frac{700 , \text{kg}}{649 , \text{m}^3} \]

Calculating this gives:

\[ D \approx 1.078 , \text{kg/m}^3 \]

Round to three decimal places:

\[ D \approx 1.079 , \text{kg/m}^3 \]

Therefore, the density of the object is 1.079 kg/m³.
