  • I think the formula is: V = SQRT( (841*L) / (C*S) ) Find V if L=8700, C=2.81, S=200^2 So, the key is just to plug in all the values: V = SQRT( ( 841 * 8700 ) / ( 2.81 * 200^2 ) ) all you have to do is plug that into a calculator, but let's work it out... -- First inside the SQRT part: 841*8700 = 7316700 200^2 = 40000 2.81 * 40000 = 112400 so it's: 7316700/112400 which can be rounded to 65.095196 so V = SQRT( 65.095196 ) I'm going to approximate by rounding it again (this time let's just go to the hundredths) V = 8.07
