The volume of a right rectangular prism is 1,000, the height is 10, and the length is 20. What is the width?

The formula for the volume of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.

Given that V = 1,000, l = 20, and h = 10, we can plug these values into the formula and solve for w:

1,000 = 20w(10)
1,000 = 200w
w = 1,000/200
w = 5

Therefore, the width of the right rectangular prism is 5.
