Daily Challenge (245 Part Series)
John wants to decorate his room with wallpaper. He's heard that having the right amount of wallpaper can be trickier than it sounds. He'd like a fool-proof way to get it just right.
John is measuring his room by length l, width w, and height h in meters. The rolls of wallpaper John purchased has a width of 52 centimeters. The length of a roll is 10 meters.
