Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. Predict how changing each variable will affect the resistance.
I just purchased crackle subway tile (3x6) for our backsplash. As I was shopping around it seemed that $12-15 per square foot was the average price. You can get cheaper but they were VERY basic. I ended up with a Sonoma tile which was hand molded and cost $20 square foot.
Cost breakdown. 1  Ceramic tile: the backsplash 1 material averages $10-$15 per square foot, although it is possible to spend much more than that on premium ceramic backsplash 1 tiles. It is recommended to always purchase 10%-20% more extra tile in case of breakage.
