정의: A sandpit or sandbox is a low, wide container or shallow depression filled with soft (beach) sand in which children can play. Sharp sand is not suitable for such use. Many homeowners with children build sandpits in their backyards because, unlike most playground equipment, they can be easily and cheaply constructed.
