Box cutting means to the excavation of the road so as to fit the road in the excavated portion this is done to make road level with the surrounding, now you have remembered that there is compaction of 6.25cm in gravel in the subbase so remaining total available ht will be 15+3.75cm, and then as usual l*b*h.
