Answer:
[tex]B = \fra{3V}{h}[/tex]
Step-by-step explanation:
Given
[tex]V = \frac{Bh}{3}[/tex]
Required
Make B the subject
[tex]V = \frac{Bh}{3}[/tex]
Multiply both sides by 3
[tex]3 * V = \frac{Bh}{3}*3[/tex]
[tex]3V = Bh[/tex]
Divide both sides by h
[tex]\fra{3V}{h} = \frac{Bh}{h}[/tex]
[tex]\fra{3V}{h} = B[/tex]
[tex]B = \fra{3V}{h}[/tex]
