Question 254175: The formula for the correction of a length c of a steel tape to allow for sag is as follows: c=w2 l3 over 24t2. Can you help?
1. w= square root ct2 over 24l3
2. w= square root cl3 over 24t2
3. w= square root 24t2c over l3
Thanks you wizards. That's what you are.

I think you are trying to say:

Solve

for

(Use the caret (Shift-6) to indicate raising to a power, so l cubed would be represented as l^3)

Multiply both sides by



Multiply both sides by



Then take the square root of both sides.



Note: Ordinarily when taking the square root of something, you need to consider both the positive and negative square roots. That is, the square root of 4 is either 2 or -2. But in this case, assuming that represents the width of something, the negative root would not make sense since width must needs be expressed as a positive number.
