What is the length of a right rectangular prism with a volume of 90 with a three in height of 5

To find the length of a right rectangular prism with a volume of 90 and a height of 5, we can use the formula for volume:

Volume = length * width * height

Given that the volume is 90 and the height is 5, we can divide the volume by the product of the height and the unknown length:

90 = length * width * 5

Dividing both sides of the equation by 5:

18 = length * width

Since we are looking for the length, we need to assume a value for the width. Let's assume the width is 2:

18 = length * 2

Dividing both sides by 2:

9 = length

Therefore, the length of the right rectangular prism is 9 units.
