Well now there's a question, I guess it depends on which side of the pond you hail from. I'm metric sorry,... so it's 1.5 meters or 1500mm so 150cm long for me, but in feet and inches? I am slightly rusty but the 30cm rulers are around about 12 inches so quick conversion to imperial is around 5 feet long.
Height its 70cm top to bottom (top of cabinet) and 50cm front to back or is that the depth but depth might be referring to the 70cm measurement well it does for me anyway you get the drift, It's a bit deeper than the usual tanks as it's a cleair aquarium (from over the other pond lol) and I went for the space for the fish not then really realising that the deeper it is the stronger the lights I need to have or otherwise a ton of rock to get the corals to the top for light then negating the reason for the deeper roomy tank for my wee tangs, so I went for the zoa garden with two red sea 160s now. I cheaped out at first on the lights but the slow evaporation of corals showed I needed better lights when all my parameters were in check, don't forget depth into the water and not only that but the height the lights will hang from the water too when buying corals or aquariums.
