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. 15
c. 5
d. 200,000

The formula for the volume of a right rectangular prism is length x width x height.

Given that the volume is 1,000 and the length is 20, and the height is 10, we can rearrange the formula and solve for the width.
Width = Volume / (length x height) = 1,000 / (20 x 10) = 1,000 / 200 = 5.

Therefore, the width is 5 units.
So, the answer is c. 5.
