Does anyone have the boot dimensions for an 8L?

I am in the process of moving and wondered how much space I have. litres wise I can find.
But I need to move my parents fish tank which is 121x51x71cm (LxDxH). The tank is around 350l. But its the height Im worried about.

I dont have access to my car as I am out of London, so any advice is welcome.

Thanks.
