The road is made of two layers:
1. A 15 cm thick concrete layer.
2. A 10 cm thick gravel sub-base layer.
Box cutting is all about how much earth you need to remove, so we only care about the final dimensions of the road profile. So, we need to consider both layers (concrete and gravel) to determine the total depth of the excavation.
1. Calculate the total thickness:
The total thickness is 15 cm (concrete) + 10 cm (gravel) = 25 cm.
We need to convert this to meters: 25 cm = 0.25 m.
2. Calculate the volume:
Volume is calculated by: Length x Width x Height (or Thickness in this case).
Length = 1000 m.
Width = 8 m.
Thickness = 0.25 m.
Volume = 1000 m x 8 m x 0.25 m = 2000 m3.
Therefore, the correct answer is Option D: 2000 m3.

According to me 1000*8*0.15-1200 over sub base.
1000*8*0.10-800 for gravel. Total-2000 cum.
1000*8*0.10-800 for gravel. Total-2000 cum.

Total volume = L*B*D. So 1000*8*(25/100) = 2000 cum.
