Answer:
378 cans in total
Step-by-step explanation:
The way I understood it is that there's a pyramid of cans where there are ten layers, now assuming that the top of the pyramid is one can then we can say that the bottom layer (n x n) should be 10x10 cans which is 100 cans.
Now with n=10,
n-1 = 9
n x n = 9 x 9 which is 81,then repeat process u til you get 1 x 1 = 1
After that, add them together to get 378 cans.
Hopefully I was able to help...
