First, I done 20X20 to get an answer of 400.I then done 400/4mthen found the cube root of that to get 10, but this is impossible as 10X10X4 is 400, so I done 10/2 to get 5 and tested it. I got 1500.I then tried the numbers around 5, 4 and 6. 4 was smaller but 6 was bigger so I tried 7. 7 was smaller. In the end, I got an answer of 1536 cube centimetres
