How do you get area and volume of object?
The surface area of object is the sum of the area of all the faces of an object, while the volume is the area of the base of an object multiplied by its height.
What does volume and surface area have in common?
The volume of a body and the surface area arerelated but not in a direct way. For a given volume, the smallest surface area of an object is seen then the object is a sphere. As the shape flattens from a sphere, so the surface area becomes larger. When the object approaches an infinitely small thickness, the surface area approaches and infinite size.
Which cell has the greater surface area compared to its volume the large cell or one of the smaller cells?
A smaller cell has a higher surface area to volume ratio. A reason for this is volume is cubic (3D) and surface area is 2D so when surface area increases a little bit, the volume increases exponentially. And when the surface area shrinks a little bit, the volume decreases exponentially.
Does powdered or lumpy chalk have the bigger surface area?
the ratio of surface area to volume of an object is inversely proportional. that is to say, when you make the object much larger, the amount of surface area to volume goes down. when you make the object smaller, the amount of surface area compared to the amount of volume goes down. consider a cube with equal sides of 2. The volume is 2x2x2 = 8. The surface area of each side would be 2x2 = 4. Times the 6 sides ... 4*6=24. So the surface area to volume ratio would be 24 to 8, or 24/8, or 3 now make the cube smaller with equal sides of 1. Volume is 1*1*1 = 1 Surface area is 1*1 per side = 1, * 6 sides = 6. Surface area to volume ratio is 6 to 1, or 6/1, or 6. you can work it the other way too and see i'm correct. so if you take a lumpy piece of chalk and grind it into a small powder, you have taken a larger single object and made it into countless incredibly smaller objects. since you're volume is unchanged, the amount of total surface area must be much greater in the powder.
As a cell becomes smaller its surface-area-to-volume ratio?
The surface area to volume ratio decreases - assuming the shape remains similar.
