To rearrange the surface area equation \( S = \frac{1}{2} l p + B \) for the quantity \( B \), follow these steps:
-
Start with the original equation: \[ S = \frac{1}{2} l p + B \]
-
Subtract \( \frac{1}{2} l p \) from both sides: \[ S - \frac{1}{2} l p = B \]
-
Thus, the rearranged equation for \( B \) is: \[ B = S - \frac{1}{2} l p \]
This equation gives you \( B \) in terms of \( S \), \( l \), and \( p \).
