It looks like you're commenting on instructable 4x4x4 led cube:

https://www.instructables.com/id/LED-Cube-4x4x4/

You'll need the perf-board, about 5 bucks
64 LEDS, depending on source, at 10-25 cents each, do the math
Microcontroller, 5-50 dollars, depending on flavour
solder and hookup wire, negligible ~ 5 dollars
Other components (multiplexer, power supply, resistors, buttons, icsp port) 5-10 dollars.
total = 30-50 dollars.

'Cause you didn't say what you were making. Or they're a much better scrounge than you are. If you have a question on an instructable, then ask it at the bottom in the 'comments' section : )
