The volume of a right rectangular prism is 1,000, the height is 10, and the length is 20. What is the width?
A. 50
B. 5
C. 15
D. 200,000
The volume of a right rectangular prism 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.
In this problem, the volume is given as 1,000, the height is 10, and the length is 20.
Therefore, 1,000 = 20w(10).
Dividing both sides of the equation by 200, we have:
5 = w(10).
Dividing both sides of the equation by 10, we get:
0.5 = w.
Therefore, the width is 0.5, or in other words, the width is 5.
The correct answer is B. 5.
