Examples
1. Area of a Rectangle: If the length (a) is 5 units and the width (b) is 3 units, and we want to find the area (c), we can use this calculator.
2. Volume of a Cube: If the side length (a) is 4 units, and we want to find the volume (b), we can use this calculator with c as 3 (since volume = side^3).
3. Profit Calculation: If the cost price (a) is $100, the selling price (b) is $150, and we want to find the profit (c), we can use this calculator.
