How do you work out the volume of a solid cylinder?
Volume in cubic units = base area times length
How do you work out the volume of prism?
You will have to work the surface area of one of the ends and then multiply that with the length.
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.
How do you work out the volume of a tetrahedron?
The volume(cm3) of a tetrahedron is 1/3 (area of the base)X height
How do you work out the cubic size of a room?
Length times width times height = volume Or area times height = volume
How do you figure surface area to volume ratio?
You work both out from measurements of the shape and the relevant formulae.
What is the definition of hot work ratio?
The hot work ratio is the area ratio of the cast diameter and the pre-machined finished diameter.
Surface area to volume ratio example?
An example of surface area to volume ratio can be seen in cells. As cells grow larger, their volume increases at a faster rate than their surface area. This can lead to limitations in nutrient or waste exchange, as the surface area may not be sufficient to support the volume of the cell. This is why cells tend to have a small size to maintain an efficient surface area to volume ratio for necessary exchanges.
How does the ratio of surface area and volume relate to the problems of growing cells?
The rate at which the cell increases in size depends on the DNA. The ratio of the surface area (calculated: length x width x # of sides) is divided by the cell volume (calculated: length x width x height). THE VOLUME OF THE CELL INCREASES MORE RAPIDLY THAN THE SURFACE AREA, CAUSING THE RATIO OF SURFACE AREA OVER VOLUME TO DECREASE. This decrease causes cell malfunction. If the cell volume increases too much, then the ratio will decrease causing problems for the cell's regular functions.
How do you work out the volume of a diamond prism?
volume=area of the cross section x the length
How do you work out the volume of a right prism?
Its volume is its cross-section area times its length.
Large cells work better if they?
have a lower surface area-to-volume ratio, allowing for efficient exchange of nutrients and waste products through the cell membrane.

The skin area of a baby giraffe of mass 25kg is 0.8m2Assuming that giraffes remain approx isomorphic as they grow what will be skin area of the giraffe when it is fully grown of weight 1.4x104 N?
hey, are you the physics160 student of Auckland uni? I just meet the question on my practice paper. square root of area / cube root of mass = ratio the ratio is always the same, so you can work out the answer for new area of 11.9 ( mass is poportional to volume not skin area.)
