The volume of the prism is 31.25 cm cubed.
Therefore the container has a higher volume.
35 - 31.25 is 3.75.
The difference is 3.75
If 
is a number that is both divisible by 4 and 5, then
4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that 
is a solution to the system, where 
is any integer. Simply put, any multiple of 20 fits the bill.
Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have 
when 
, so the sum we want to compute is
I will assume that function f(x) = 6(0.25)^x
The domain of this function is all the real numbers.
Reflection accross the y-axis => the argument is multiplied by - 1. and g(x) is 6(0.25)^(-x).
The graph of the original function flips around the y-axis, but the domain keeps being all the real numbers.
Answer: all real numbers
