The total number of boxes that are in the container are:
30 boxes.
<h2>Step-by-step explanation:</h2>
It is given that:
A container has 5 rows of boxes that are stacked 3 boxes high and 2 boxes deep.
This means that the total number of boxes is calculated as the product of number of boxes in a row multiply by the number of boxes along a column and the boxes above other i.e. the number of boxes in depth.
The "compound amount" formula is A = P(1+r/n)^(nt), where P=original investment, r=interest rate as a decimal fraction; n=number of compounding periods, and t=number of years.
Then A = $12000 * (1+0.08/2)^(2*11) = $12000(1.04)^(22) = $28,439.03 (answer)
