Solution Steps
To find the smallest possible inside length of a cubical tank that can hold 360 liters of water, we need to determine the side length of a cube whose volume is 360 liters. Since 1 liter is equivalent to 0.001 cubic meters, we first convert the volume to cubic meters. Then, we find the cube root of this volume to get the side length of the cube. Finally, we round the result to the nearest 0.01 meters.
Step 1: Convert Volume to Cubic Meters
The volume of the tank is given as \( 360 \) liters. To convert this to cubic meters, we use the conversion factor \( 1 \, \text{L} = 0.001 \, \text{m}^3 \):
\[
\text{Volume in cubic meters} = 360 \, \text{L} \times 0.001 \, \text{m}^3/\text{L} = 0.36 \, \text{m}^3
\]
Step 2: Calculate the Side Length of the Cube
The volume \( V \) of a cube with side length \( s \) is given by the formula:
\[
V = s^3
\]
To find the side length, we take the cube root of the volume:
\[
s = V^{1/3} = (0.36)^{1/3} \approx 0.7114 \, \text{m}
\]
Step 3: Round the Side Length
We round the calculated side length to the nearest \( 0.01 \) meters:
\[
s \approx 0.71 \, \text{m}
\]
Final Answer
The smallest possible inside length of the tank is \\(\boxed{0.71 \, \text{m}}\\).
