[00:00:00]Did you know that companies like Amazon use differential calculus to save millions on cardboard? When designing a box from a flat sheet, the goal is to maximize the volume V X while keeping material costs low.

[00:00:13]If you cut out squares of size X from the corners of a sheet, the volume is defined by a cubic function.

[00:00:20]To find the exact sweet spot where the volume peaks, you take the derivative of the volume function with respect to X, set it to zero V X = 0, and solve. This identifies the critical point where the slope of the volume curve becomes perfectly flat at its highest peak.
