The formula, when solved for B is, [tex]\frac{1}{2}(A-PH)[/tex].
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
[tex]A-PH=PH-PH+2B\\A-PH=2B\\2B=A-PH[/tex]
Dividing both sides by 2
[tex]\frac{2B}{2}=\frac{A-PH}{2}\\\\B=\frac{1}{2}(A-PH)[/tex]
The formula, when solved for B is, [tex]\frac{1}{2}(A-PH)[/tex].
