3m (Vol is 3x3x3 = 27)
Vol = 2*1*3 cm3 = 6 cm3
Vol = Pi/4 x D2 x HorVol = Pi x r2 x HwhereD = diameterorr = radiusandH = height
Vol = 10 cm * 5 cm * 40 cm = 2,000 cm3
Volume of a cylinder is easy: Vol= [(pi) x radius^2] x height of cylinder] Where Pi= 3.1416 approx and radius = 1/2 of cylinder diameter The volume of a prism is complicated because it depends on the type of prism. for a regular shape prism the formula is : Vol = (area of base) x height If the prism is a "union" of differents shapes, you have to split the prism in smaller/single/easy shapes and calculate the volumes individually and then add the resulting volumes
No, diluting a 30 vol hair developer with water will not change the volume strength of the developer. To make a 20 vol developer, you would need to mix the 30 vol developer with a neutralizing solution or a lower volume developer.
Yes. 10 vol developer is 25% peroxide.
Mix equal parts of the 10 vol. and 20 vol. developer to create a 15 vol. developer solution. This will give you a balanced formula that combines the properties of both developers to achieve the desired volume strength.
30 vol is stronger
The difference between 10 and 20 volume developer is the strength or potency of the developer. 20 volume developer is stronger and lifts the hair color more effectively than 10 volume developer. The choice between them depends on the desired level of lift and hair color result.
I would like to substitute 9 vol for 20 vol fit grey coverage
Yes, this will work, but I recommend using 20 volume developer instead of 30 volume and watch the hair closely.
It depends on the brand and type of permanent color being used, as well as the desired level of lift. Check the manufacturer's instructions on the color product for the recommended developer volume to mix with the color. Generally, 20 volume developer is used with permanent color for standard lift, while 30 volume developer may be used for additional lift or gray coverage.
I am talking about hair developer
Developer of any volume won't do much of anything by itself. It will need to be mixed with a lightener and yes, it will be suitable for your needs once it is mixed with a lifting agent.
particularly, yess. it depends on what hair dye it is for the vol. of the developer. but, MOST hair dyes, require 20-30 vol. happy hair dyinng.
