Answer 1

To find the density of the cube, we can use the formula:

\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]

1. First, we need to calculate the volume of the cube: \[ \text{Volume} = \text{side length}^3 = 2 , \text{m} \times 2 , \text{m} \times 2 , \text{m} = 8 , \text{m}^3 \]

2. Next, we can use the mass given (40 kg) to find the density: \[ \text{Density} = \frac{40 , \text{kg}}{8 , \text{m}^3} = 5 , \text{kg/m}^3 \]

Therefore, the density of the cube is 5 kg/m³.
