Evaluate: \((0.06^3 + 0.02^3) + (0.3^3 + 0.1^3)\).

1. 0.016
2. 0.028
3. 0.036
4. 0.048

Correct answer: 0.028

Solution

Calculate the cubes: \(0.06^3=0.000216\), \(0.02^3=0.000008\), \(0.3^3=0.027\), and \(0.1^3=0.001\). Adding them gives \(0.000216+0.000008+0.027+0.001=0.028224\), which matches the option \(0.028\) to the given precision.
