I'm having trouble understanding what you wrote. Can you state this again in your native language (I'm guessing Spanish). Maybe @LAL can help if he's around.

You can wire multiple strips together, but the LEDs farthest from the power feed may be dimmer because the traces may not handle 6 amps without excessive voltage drop. You may need to run some additional power wires in parallel, maybe 18 AWG (1.0mm diameter) wire, and connect the strips to this power wire.

Photo number 6 shows the control box can only handle 3 amps. A single light strip consumes about 2 amps, so you cannot use a the included control box for 2 or more light strips.

If you want to use a single control box, you need to use a higher power version, like sku.175075. sku.175075 can handle 18 amps, or up to 9 of these RGB LED strips.

The print on the box (pic 6) is "3A * 3", doesn't that mean "3A per color" (as with most other controllers?)
But anyway: this would be a total of 9A, or 108W (12V x 9A), and 5 complete strips of these will need 112,5W (22,5W x 5).
If you can cut 1 meter (for a total length of 24 meters), it would need only 108W for the 24 meters.
But running these electronics at their limit... it's chinese! ;-)
And like desolder wrote, firing the complete 3A on one of these thin traces will cause a big voltage drop, so after some meters the led's surely will get dimmer.
