Volume fraction. In chemistry and fluid mechanics, the volume fraction is defined as the volume of a constituent Vi divided by the volume of all constituents of the mixture V prior to mixing: [1] Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18. It is the same concept as volume percent (vol%) except that the latter is ...
The video explains how to calculate the volume of a rectangular prism with fractional dimensions. It emphasizes that volume equals the area of the base times the height. To find the volume, multiply the length, width, and height. The video also shows how to simplify fractions during multiplication. Created by Sal Khan.

- He doesn't really thoroughly explain the part where he multiplies all of the fractions. I got confus...What he means is 7 * 3 * 3/6 * 5 * 7. It's equal to 7/7 * 3/6 * 3/5. That's 1 * 1/2 * 3/5, which equals 3/10. Do you understand now? If you need mo...
- i didn't know geometry was so hard!true! its really fun though when you get the hang of it
- How do you express the answer?Any unit to the third power because we are talking about 3D volume units. E.g. cm^3 or inches cubed.
- Does anyone read the comments when there bored 🥱yes but cant just be yes because khan said so
- I'm not sure if this is right but I think the equation is Length x width x height Tell me if I'm rig...Yes, the volume of a rectangular prism is always length x width x height. Good job!
- What's the difference between V=bh and V=Bh?In geometric formulas, b usually refers to the length of the base of a 2-dimensional figure. B usually refers to the area of the base of a 3-dimens...
- i do not under stand and i want to be able to ace most of my bench mark testIt is basically the same as a regular rectangular prism. You multiply base and height (length x height x width).
