Surface area of a cylindroical box , which includeds the two circular ends.
S.A. - 2pir^(2) + 2pirh
Factor
S.A. = 2pi r ( r + h)
Where
pi is the constant ; 3.141592.....
'r' is the radius of the cylinder
'h' is the height(length) of the cylinder.
Flatworms have a higher surface area/volume ratio compared to a cylindrical worm, this is one of the reasons for flatworms to have the structure they do.
times leagth times weith
Volume = cross-section area*length
If it is a rectangular box, then volume = length*breadth*height, where each is measured in inches. If it is a cylindrical box, then pi*radius2*height, where the radius and height are measured in inches.
Volume = cross-sectional area times height
Remember the eq'n from antiquity/ C = pi d d = C / pi That is the circumference divided by pi(3.141592....)
A rain gauge is commonly used to measure the amount of rainfall received by an area. It consists of a cylindrical container that collects rainwater, allowing for measurement of the water level to determine the amount of precipitation.

Diameter multiplied by pi multiplied by the height is the area of a cylinder. If your looking for a cylindrical ring, like a dougnut, then compute the area of the smaller cylinder (the hole) and subtract this from the area of the larger cylinder (the doughy goodness)
The formula for calculating the volume of a solid using the area element in cylindrical coordinates is V r dz dr d.
The premise of your question is false. Take, for example, a juice box.

Biggest surface area to volume ratio.
Volume = cross-section area*length
If it is a rectangular box, then volume = length*breadth*height, where each is measured in inches. If it is a cylindrical box, then pi*radius2*height, where the radius and height are measured in inches.
Volume = cross-sectional area times height
It depends also of what the box is made of
