Original volume= 1000*8*(15+10) = 2000m3.
Cut off volume= 1/4 * 2000 = 500m3.
Box cutting=2000-500= 1500m3.
Cut off volume= 1/4 * 2000 = 500m3.
Box cutting=2000-500= 1500m3.

15/4 = 3.75 then,
10cm - compaction 3.75 = 6.25 cm.
10cm - compaction 3.75 = 6.25 cm.

@Rishabh.
Why you divide 2000 by 4?

Box cutting in road crust= 1000 * 8 * (0.15+0.10).
= 2000m^3.
= 2000m^3.

I think the answer is 2000m3 is correct.

Original volume= as you know = 2000.
Cutt off volume= 1/4 of the original volume.
1/4x2000 = 500cum.
So, box cutting in road = 2000 - 500 = 1500 cum.
Cutt off volume= 1/4 of the original volume.
1/4x2000 = 500cum.
So, box cutting in road = 2000 - 500 = 1500 cum.
