A rectangular floor measures 2 by 3 meters. There are 5 white, 5 black, and 5 red parquet blocks available. If each block measures 1 by 1 meter, in how many different color patterns can the floor be parqueted?
* 104 * 213 * 577 * 705 * 726
i assume that here we have 6 blocks. why we can't just get 5^3 for each block,instead of 3^6? i can't get the logic
