1. Enter the dimensions of the room (height, length, and width in meters, wall width in inches).  
2. Enter the dimensions of the gate and window (in meters).  
3. Enter the dimensions of a single brick (in inches).  
4. Click the **Estimate Requirements** button to calculate the number of bricks and mortar volume.  
5. Reset inputs using the **Clear Inputs** button.
