Answer:
4y+3
Step-by-step explanation:
The answer that you have is most likely right, since the grouping did not change.
So do 21/7 to give you how much they do in a day. The answer is three so they do 3 aceres in a day.
So to find out the answer, you need to find out the dimensions of each cube. So for the 1331, it's 11 x 11 x 11. So you know that would be 11 meters high. Now the next cube. Then there's another 1331, so that would be another 11 meters high. Then 729, also 9 x 9 x 9, so that's going to be 9 meters high. Then add all the cube square roots. 11 + 11 + 9 = 31. So the height of the stacked boxes will be 31 meters.
