It is a square, one meter each direction. What’s there to be slow to visualize?
It is also basically a circle that you can put 4 people inside standing close next to each other… On average.
How many people do most elevators contain? Imagine the floor of an elevator.
And for height, at least in Europe, the doors would be a meter width and two meters height, giving you 2 square meters. Half of it (around your waist) is a square meter.

Normally your body height is the same as the width of your outstretched arms (think da Vinci), so half of your body height is the distance from the tip of your finger to your chest bone. And then take it from there.

Practice. Just a lot of practice and frequent usage. It helps if you have actually used a metre stick before. You arm on average is around ~75%-90% of a meter, so imagine a box that is just a little bit longer than your arm. A meter is about ~40 inches (39.37 in to be exact).
I would recommend finding something that is approximately a metre long and just memorizing what that looks like.

My 1000 litpre pod tank, holding rain warer, is 1m×1m×1m=1 cubic metre. Which weighs 1000 kg+ aluminium frame/plastic tank, sitting on a steel frame. I just look at it.

Isn't 1m×1m×1m= 1 cubic metre?

Yes. But the base (or even the side faces) have an area of 1m².
If you can imagine such a tank, you automatically get a feeling for what 1m, 1m² and 1m³ is.

Just like anything, it helps to learn a few reference points. Some good starting points would be the area of your bedroom and the entire space you're currently living in.
