Volume
"There is a cube shaped box with a side length of 6. What is the volume?"
Jasmine and Mulan are debating in class. Jasmine says you can find the volume even if you only know one side length. Mulan says you can't solve this problem since it doesn't tell you the length, width and height. Who is correct and why?
Jasmine is correct. Cubes have all equal sides so we only need to know one side. To solve this problem, you would do:
V = 6 x 6 x 6
