Oh no! The battery on your car is dead and you have an important meeting to get to. Luckily you prepared and have a battery on hand, all you need to do is replace it. You grab your wrenches and begin to remove the battery. Since this car is a newer model you know the bolts are measured in metric units. On the first bolt, the 14mm wrench is too big. You try the 12mm wrench and find it to be too small. Which wrench would you try next?

The next wrench you would try is a 13mm wrench.

If the 14mm wrench is too big and the 12mm wrench is too small, the next wrench you would try is the 13mm wrench. Since the bolt on the car is measured in metric units, you should keep trying different metric-sized wrenches until you find one that fits properly. In this case, you would try the 13mm wrench to see if it fits the bolt correctly.

Since the 14mm wrench is too big and the 12mm wrench is too small, you should try the 13mm wrench next.
