Rearranging formulas, step by step
A formula is only useful in the direction you need it.
The question
Solve V = ⅓Bh for B.
Solve V = ⅓Bh for B
V = ⅓Bh
3V = Bh
= B
B =
- V = ⅓Bh is the volume of a cone or pyramid. To make B the subject, undo everything that is being done to it.
- Undo the next operation on both sides. V = ⅓Bh becomes 3V = Bh.
- Divide both sides by what multiplies it. 3V = Bh becomes 3V/h = B.
- Write it with the letter you want on the left. 3V/h = B becomes B = 3V/h.
How it works.
- 01
V = ⅓Bh is the volume of a cone or pyramid. To make B the subject, undo everything that is being done to it.
- 02
Undo the next operation on both sides. V = ⅓Bh becomes 3V = Bh.
- 03
Divide both sides by what multiplies it. 3V = Bh becomes 3V/h = B.
- 04
Write it with the letter you want on the left. 3V/h = B becomes B = 3V/h.
