A wooden block in the shape of a cube has a side length of 0.3 m and a mass of 18.954 kg.

What is the density of the block?
Enter your answer in the box.
[tex]\[ \square \ \text{kg} / \text{m}^3 \][/tex]



Answer :

To determine the density of a wooden block in the shape of a cube, we need to follow these steps:

1. Calculate the volume of the cube:
- The formula for the volume [tex]\( V \)[/tex] of a cube is given by:
[tex]\[ V = \text{side length}^3 \][/tex]
- The side length of the cube is 0.3 meters.
- Therefore, the volume [tex]\( V \)[/tex] is:
[tex]\[ V = (0.3)^3 = 0.027 \text{ cubic meters} \][/tex]

2. Use the mass of the block to find the density:
- The formula for density [tex]\( \rho \)[/tex] is given by:
[tex]\[ \rho = \frac{\text{mass}}{\text{volume}} \][/tex]
- The mass of the block is 18.954 kg.
- The volume of the block we have calculated is 0.027 cubic meters.
- Therefore, the density [tex]\( \rho \)[/tex] is:
[tex]\[ \rho = \frac{18.954 \text{ kg}}{0.027 \text{ m}^3} \approx 702 \text{ kg/m}^3 \][/tex]

Hence, the density of the wooden block is [tex]\( 702 \text{ kg/m}^3 \)[/tex].
