There are two possible answers for this question.
If the aquarium has a glass lid, more glass will be needed
If the aquarium has no glass lid (like normal) less glass will be needed.
To find the two solutions find the area of each side. Because the sides are paired, you only have to calculate the area 3 times.
We start with the sides
200cm*600cm=120000cm squared*2 =240000cm squared
the small sides
200cm*300cm=60000cm*2= 120000cm squared
and the top and bottom
300cm*600cm= 180000cm....
with no glass lid the amount of glass needed is 540000cm squared
with a glass lid the amount of glass needed is 720000cm squared
