how/where did the concord hold 42 of these tanks ?
Pictured is a 750 gallon tank and the concord had a fuel capacity of 31,500 gallons. Thats he equivalent of 42 of these tanks

Here's two pictures showing how the tanks were arranged:
There were actually 13 fuel tanks on board.
Just realized how many things have to work smoothly in an aircraft. So many fuel pumps and they all have to distribute the fuel correctly without failing.
Are you familiar with Admiral Cloudberg's writeups of air disasters? https://admiralcloudberg.medium.com/ It's exactly what you're talking about: a lot of things have to go right on the plane, in the cockpit and on the ground.
By the way, that oddly shaped hole in the middle is where the main landing gear folds into.
Funnily enough the volume of fuel is approx half the volume of the entire plane, and it uses fuel at double the rate of a 747.
Engineering is awesome.
Like most planes, the wings are mostly fuel tanks. https://www.heritageconcorde.com/fuelgeneral
Your picture shows the scale quite well, actually. Imagine that girl sitting in the cockpit and then imagine the size of the barrel compared to that.
Fuel is typically measured by weight in aircraft so "a full tank" might be different besed on the density of the fuel.
The wings and body.

Pretty much distributed over the entire area of the plane:

At least this picture explains that oddly shaped hole in the middle: It's the place for the main landing gear to fold in.
Taking an absolute guess here..
But could it be the difference between raw capacity (as shown in the tank image) vs compressed?
My thinking here is from when F1 teams started chilling down the fuel to fit more in a tank.
The gains from increased density were extremely marginal, but then again F1 is a marginal gains game. Maybe you could push a couple extra % more in some parts of the race to gain or secure track position but it wouldn't change overall performance. That's also why the FIA switched to fuel weight instead of volume.
On a plane like this it wouldn't make a difference as weight is more important than volume.
Fuel is a liquid. What did you learn in school about liquids?
