Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
How do you find the dimensions of a rectangular prism if you have the surface area?
It is not possible. For example, the prism could be tall and thin, or short and thick, and either way have the same surface area.
What does this mean 4millimeters x 2.3meters x 24meters?
It means that someone has recorded the dimensions of a thin object with rather a large area, possibly with the aim of calculating its volume. However, it is equally possible that the dimensions are recorded to establish its surface area (for painting?).
How do you find the length width and the height of a rectangular prism if you already have your surface area?
You cannot find a unique solution because blocks of different shapes and volumes can still have the same surface area.You can find the dimensions of a cube with the given surface area; it is the largest volume of a rectangular prism for a given surface area.A cube has six equal square sides. Take the total surface area "At", divide this by 6 to get the area of one side "As":At / 6 = AsThe length Ls of one side of the cube is the square root of As .Ls = sqrt (As ) = sqrt (At / 6 )All the edges of a cube are of course the exact same length.Another solution is a very thin square prism (almost a sheet but with a finite thickness) with the top and bottom just slightly less than half the surface area; the remainder has to be spread out along the edge which can be arbitrarily narrow.Theoretically you can have a very long rectangular prism and so very large values for the length if the height and width are very small and still have the surface area set out in the problem.
How do you get the formula of an open cylinder from the surface area of a cylinder?
The question does not specify what the required formula is for: the volume of an open cylinder, height, radius, surface area, etc. Furthermore, information on the total surface area of a cylinder will not provide sufficient information. A short wide cylinder can have the same surface area as a tall thin one. For example, radius 5 cm and height 4 cm or radius 4 cm and height 7.5 cm or radius 3 cm and height 12 cm or radius 2 cm and height 20.5 cm etc all have the same total surface area. But in each case the value of the other measure, for the open cylinder will be different.

Why are root hair cells of a plant long and thin?
Large surface area.
Three ways in which the lungs are adapted for gas exchange?
Many alveoli-increases surface area for gas exchange Thin alveolar wall-allows gases to diffuse easily and fast Thin capillary wall-easy diffusion Inner wall of alveoli-allows gases to dissolve, which they need to enter the capillary
What is the main job of the alveoli?
The alveoli, the small sacs of air at the ends of the terminal bronchioles, are the sites of the exchange between oxygen and carbon dioxide.
What are thin-walled sacs in the lungs are?
the thin-walled sacs in the lungs are the alveoli. they are tiny are sacks in your lungs.

11 Most anthophyte leaves are thin with a large surface area This structure enhances the plant's ability to?
take in water
What 2 features of a villi help the small intestine function?
Large surface area Thin- Short distance for diffusion
Adaptive feature of trachea and alveoli?
Trachea have cartillage rings which support it. And the Alveoli has large surface area for diffusion and its moist and thin.
What two feartures of root hairs make them well desinged for absorbing nutrients?
large surface area thin cell membrane
What makes villi good at absorbing food?
large surface area, thin epithelium, highly profused with blood vessels and lymphatics
How do you call the special structures for absorption in the small intestine?
thin lining good blood supply very large surface area
