The formula, when solved for B is, \frac{1}{2}(A-PH).

Step-by-step explanation:

Given,

Formula used to find surface area of a rectangular prism

A = PH + 2B

Solving the formula for B;

Subtracting PH from both sides

A-PH=PH-PH+2B\\A-PH=2B\\2B=A-PH

Dividing both sides by 2

\frac{2B}{2}=\frac{A-PH}{2}\\\\B=\frac{1}{2}(A-PH)

The formula, when solved for B is, \frac{1}{2}(A-PH).
