Tropical Rainforest: Animals Tropical rainforests support a greater number and variety of animals than any other biome. One of the reasons for this great variety of animals is the constant warmth. Tropical rainforests also provide a nearly constant supply of water and a wide variety of food for the animals.
Dimensions. Wardrobe dimensions depend on the builder or designer. Most wardrobe cabinets typically are 24 inches deep, but can be as narrow as 18 or even 12 inches in depth. Height also depends on application, but standard height is usually no more than 72 inches. Width varies anywhere from between 24 inches to more than 96 inches.
It completely depends on what they plan on putting on the shelves. For most ordinary books, 8 inches is enough and the 12 inch shelves commonly used are too deep. Years ago I actually had shelves made that were only 6 inches deep so I could put them in a hallway to hold paperbacks.
