We found the biggest by stacking all the cubes together from one to six . We know that the top should be six as you times the top by five and the rest by four.After be multiplied one to five by four and six by five we add all the answers together. That gave us the answer (90) The six had to be on the top and it didn't matter where the rest of the numbers were.
To find the lowest we had to make a cuboid using the cubes ,three on top and three on the bottom . Then we multiplied the numbers by what it should be and add the numbers together. We made sure that we made a tight, firm shape that showed as little cube as possible. The place with the least sides showing was at the bottom middle (it had only two sides showing)so naturally, we put six there.
The answer was 60.
