what is the length of a right rectangular prism with a volume of 90 worth of 3 and height or 5

To find the length of a right rectangular prism, we need to divide its volume by the product of its width and height.

The given volume is 90 cubic units.
The given width is 3 units.
The given height is 5 units.

So, the length (L) can be found as:
L = Volume / (Width * Height)
L = 90 / (3 * 5)
L = 90 / 15
L = 6

Therefore, the length of the right rectangular prism is 6 units.
