PSAT Math Multiple-Choice Practice Question 611
Question: 611
If the volume of a pyramid is given by the formula V = 
lwh, where V is the volume, l is the length, w is the width, and h is the height, what is the width of the pyramid in terms of the other variables?
Correct Answer: C
Explanation:
(C) This problem is simply asking you to isolate the w variable. To begin, let's move the constant to the left side of the equation by dividing both sides by 
.
Dividing by is the same as multiplying by 3. (Remember that dividing by a fraction is the same as multiplying by its reciprocal.) So we're left with:
3V = lwh
Next, let's divide both sides by l:
The final step is to divide both sides by h, giving us our final answer:
This is choice (C).
