Video Summary

The problem involves determining the smallest number of white blocks needed to construct a large cube made up of eight small cubes, using either four white blocks or one white and one red block per small cube. The large cube is 2x2x2, totaling eight small cubes. By examining visible white and red faces on the large cube, the calculation assumes using minimal white blocks through mixed block construction where possible. Counting the visible and assumed hidden blocks, the solution concludes that 14 white blocks are necessary, making option D the correct answer.
