Video Summary

The problem involves determining the number of white wooden blocks used to construct a cube made of three kinds of blocks: white (1 unit), dark grey (3 units), and light grey (5 units). The entire cube occupies a volume of \(3 \times 3 \times 3 = 27\) units. The light grey and dark grey blocks together take up 16 units of volume (10 units from two light grey blocks and 6 units from two dark grey blocks). Subtracting the grey blocks' volume from the total gives \(27 - 16 = 11\), hence there are 11 white blocks used. The answer is B.
