To compute the surface area of the chocolate tower, we need to find the surface area of each individual side and then add them together. The chocolate tower has 5 sides - the bottom square base, the four rectangular sides, and the top square base.
First, let's calculate the surface area of the base:
Surface area of the base = side * side
Surface area of the base = 16 in * 16 in
Surface area of the base = 256 in^2
Next, let's calculate the surface area of the four rectangular sides:
Surface area of one rectangular side = height * length
Surface area of one rectangular side = h * 16 in
Surface area of one rectangular side = 13.86 in * 16 in
Surface area of one rectangular side = 221.76 in^2
There are four sides, so the total surface area of the four rectangular sides would be:
Total surface area of the four rectangular sides = 4 * 221.76 in^2
Total surface area of the four rectangular sides = 887.04 in^2
Finally, we add the surface area of the base and the four rectangular sides:
Surface area of the chocolate tower = surface area of the base + total surface area of the four rectangular sides
Surface area of the chocolate tower = 256 in^2 + 887.04 in^2
Surface area of the chocolate tower = 1143.04 in^2
Therefore, the correct answer is 1143.04 in^2.
