Can't tell for sure...is the bottom glass of that tank cracked all the way across? And then some silicone smeared over the crack as a "repair"? It appears that way; hard to tell when one of the pictures seems to be of nothing but a wet floor.
If so, forget it. Fixing this would take a bunch of time, effort, experience and luck. No acrylic, you would need a complete removal of all interior silicone, likely the removal of the pieces of the bottom panel, replacement with a new pane of at least similar thickness, a complete re-seal of the interior seams...this is a job or someone who has already built some tanks from scratch and has a good feel for what's needed. It's a tedious, labour-intensive process and not cheap in terms of time or money. You'd be throwing good money after bad.
The only reason to possibly attempt this would be the desire for a challenge; in terms of practicality, that tank is a write-off as an aquarium. You now have a leaky snake cage.
