9. Cube Density 0210 pts possible
The mass of a solid cube is 1230 g, and each edge has a length of 5.69 cm.
Find the density of the cube.
Answer in units of $\mathrm{kg} / \mathrm{m}^{3}$.
Solution
Solution Steps
Step 1: Calculate the Volume of the Cube
The volume \( V \) of a cube is given by the formula:
\[
V = \text{side length}^3
\]
Given that each edge of the cube is 5.69 cm, we convert this to meters:
\[
5.69 \, \text{cm} = 0.0569 \, \text{m}
\]
Now, calculate the volume:
\[
V = (0.0569 \, \text{m})^3 = 0.0001843 \, \text{m}^3
\]
Step 2: Convert Mass to Kilograms
The mass of the cube is given as 1230 g. Convert this to kilograms:
\[
1230 \, \text{g} = 1.230 \, \text{kg}
\]
Step 3: Calculate the Density
Density \( \rho \) is defined as mass per unit volume:
\[
\rho = \frac{\text{mass}}{\text{volume}} = \frac{1.230 \, \text{kg}}{0.0001843 \, \text{m}^3}
\]
Calculate the density:
\[
\rho = 6674.5 \, \text{kg/m}^3
\]
Final Answer
The density of the cube is \(\boxed{6674.5 \, \text{kg/m}^3}\).
