Xiaoxiao and Naughty use a rope to measure the wood in the yard. As a result, the rope was 1.8 meters longer than the wood, and the difference was 0.3 meters when the rope was folded in half and measured again. It's embarrassing for Xiaoxiao and naughty. Please do the math for them, how long is the wood?
