One day, Xiaoming and Dongdong used the temperature difference to measure the height of the mountain. The temperature measured by Dongdong at the foot of the mountain is 4°C, and the temperature measured by Xiao Ming at the top of the mountain is -12°C. It is known that the temperature in this area drops by 0.8°C for every 100-meter increase in altitude. How many meters is this mountain high?
一天小明和冬冬利用温差来测量山峰的高度．冬冬在山脚测得的温度是4℃，小明此时在山顶测得的温度是-12℃，已知该地区高度每升高100米，气温下降0.8℃，这个山峰高多少米？
