Answer:
C)
Explanation:
Isolate the variable, B. Note the equal sign, what you do to one side, you do to the other.
![V = (1)/(3) * B * h](https://img.qammunity.org/2021/formulas/mathematics/high-school/2ydbc1l6e39zas2sfx49262y8x07gua2bv.png)
First, divide h from both sides of the equation:
![((V))/(h)= (((1)/(3) * B * h))/(h)](https://img.qammunity.org/2021/formulas/mathematics/high-school/yve6ze13yevmy0egkvt6e0y9q0fk83np45.png)
![(V)/(h) = (1)/(3) * B](https://img.qammunity.org/2021/formulas/mathematics/high-school/6btijdyu4mlu8lu42rwjc0arxwj2dxoxd1.png)
Next, isolate the B. Multiply 3 to both sides:
![((V)/(h)) * ((3)/(1) ) = ((1)/(3)) * ((3)/(1)) * B](https://img.qammunity.org/2021/formulas/mathematics/high-school/ud406gwaldisgmosuwky5cxb3v3fecqqcy.png)
![B = ((V)/(h) * (3)/(1) )](https://img.qammunity.org/2021/formulas/mathematics/high-school/iuh2pmd8csmeq3tin3igtvhtlcin28v2g3.png)
Simplify. Multiply straight across:
![B = ((V)/(h) * (3)/(1) ) = (3V)/(h)](https://img.qammunity.org/2021/formulas/mathematics/high-school/35g0d4wp7k9jwga0x8k9dm49yd14fg9q9v.png)
C)
is your answer.
