Is a 45cm by 31cm by 31cm aquarium is big enough for 3 gerbils?

Question

i mean 50 by 31 by 31

Answer 1

for 3 gerbils at least get a 20 gallon.  a 10 gallon is just a bit too small.  because of their active behavior they need as much room as possible.  

Answer 2

Centimeters? That, by no means, is big enough for three gerbils. The measurements sound like the measurements of a 10 gallon tank. It's big enough for one gerbil, or a pair of gerbils IF you have a tank topper like these ones:
