Hint: This is a cube, so what lengths are the other sides?

Take an A4 sheet of paper and fold it into four equal width strips. Then fold this into an open cuboid and join together with sellotape. Label this cuboid A. A

Again take another A4 sheet of paper and fold also into four equal width strips. Similarly, fold this into an open cuboid and join together with sellotape. Label this cuboid B. B

Q: Is the volume of cuboid A less than, equal to or greater than the volume of cuboid B ? Firstly, write down your intuitive answer. Now, working with rulers and calculators, solve this problem. A B
