I am pretty sure that this question belongs in the maths section not the geography section.
Anyways, the answer is simply to find.
First make sure the units are the same.
Secondly, subtract the first sphere number by the second.
The answer is 35 cubic in.
Hope I helped!!! :)
These subs are useful in studying the ocean floor, where it is so deep that divers would be crushed by the water pressure. For example, research submersibles are used to study shipwrecks like the RMS Titanic.
