The depth would have to have a value of 1. For example, a slab 60" long by 24" wide by 1" deep would have the same surface area as volume. Examples: Area = LxW (60x24=1440 sq inches). Volume = LXWXD (60x24x1=1440 cubic inches). In this case, the volume has the same value as the surface area
A practical need to calculate surface area arises, for example, when you need to paint your house. The amount of paint you need is proportional to the surface area you want to paint.
The area would be 120 inches but you need a height to get the volume The area would be 120 inches but you need a height to get the volume
Surface area, is used to paint a house or wrap a present and volume is used when you need to know how much water to put in your fish tank or water bowl
Some practical real world examples why surface area is important:If you want to paint a house, you need to know the surface area to determine how much paint to buy.If you want to plant grass on a dirt lot, you need to know the surface area to determine how much grass seat to use.If you want to sew a dress, you need to know the surface area of the dress (dress size) to know how much material you need.If you want to make money mowing lawns, you need to know the surface area of the lawn to know how much to charge for the work.If you want to put carpet in a living room, you need to know the surface area of the room to know how much carpet you will need.If you are making a label for a soup can company, you will need to know the surface area of the can.
you need measurements to figure out surface area. the simplest way to figure out the whole area of a dodecahedron is to find the surface area of one pentagon, then multiply by 12 (the number of sides of a dodecahedron)
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
If the cell has a simple geometric shape, there are formulae that can be used. Otherwise you need to measure the surface area and the volume.
To tackle this you first need to know the equations for both volume and surface area. The surface area of a cube is 6x2 where x is the side length. The volume of the cube is x3. Thus x is the cube root of the volume. We can substitute this in to the surface area equation and say that the surface area of a cube is 6volume2/3 This can also be rearranged to say that the volume of the cube is (the surface area/6)1.5
Capillaries are tiny blood vessels. They need to have a greater surface area to volume ratio because they need to diffuse oxygen quicker.
That's impossible, you need to have three dimentions to find a volume.
A triangle is a flat area, therefore it has a surface area, not a volume. Density is unrelated to the problem; you would need some additional information to calculate the surface area.
Volume
When size of cell increases ,its surface to volume ratio decreases , control of cell activities become difficult , contact area with surrounding decreases .
Surface area: when you want to paper a room or pain it. Volume: When you want to know how much stuff you can cram into the boot of your car, or in a fridge, suitcase.
To increase surface area, a cell will have to grow. But most cells have restraints that interfere with too much growth. Only cancer cells don't bide by the rules.
In many crafts and trades an understanding of surface and volume are quite fundamental to the practice. Consider the plastering of a building, or the quantity of frosting needed for a cake. Both need to know the area surface of the object, and also need to know the volume of the surfacing material. With more practice these will become familiar and comfortable concepts.
When asked to work out the lengths of its edges and its surface area.
