For example: A rectangular prism has a height of 4 cm, a width of 5 cm, and a volume of 60 cm^3. What is the length of the rectangular prism?
Solution:
Volume of a rectangular prism:
V = length * width * height
60 = l*5*4
60 = 20l
60/20 = 20l/20
3 = l
Therefore, the length of the rectangular prism is 3 cm.
