Why isn't the base of the cylinder included in the TSA of the bird bath??

Expert Answer:

Total Surface area of any object refers to what you can see on the outside. If you will see here, the top of the cylinder is open (since its a bird bath) and hence, its surface area need not be taken into account whereas on the other hand, at the other end we have a hemispherical depression and hence, we don't need to account for the area of base of the cylinder, but instead need to consider only the CSA of the hemisphere.
