SUMMARY
The problem involves constructing a cubical box with a volume of 125 cm³, requiring precision in the edge length to maintain the volume within a tolerance of 3 cm³. The volume formula V = a³ leads to the differential equation dV = 3a²da, where a represents the edge length. By substituting a = 5 cm and dV = 3 cm³, the solution for da reveals the acceptable variation in edge length to ensure the volume remains between 122 cm³ and 128 cm³. This approach provides a clear method for determining the necessary precision in the box's dimensions.
