Sub base =10 cm.
And we take base = to or less than about sub base = 10 cm. Total depth of cutting = 20 cm. Therefore, V cutting = 1000 x 8 x .2= 1600m3.
We excavate less than 1600 so the nearest option is 1500. So correct answer is 1500 m3.

Orginal volume = 1000m * 8m * (15cm+10cm),
= 1000 * 8 * 0.25cum,
= 2000 cum.
Cutt-off volume = (1/4) * original volume.
= (1/4) * 2000cum,
= 500cum.
So, Box cutting in road curst = (2000-500).
= 1500cum.
= 1000 * 8 * 0.25cum,
= 2000 cum.
Cutt-off volume = (1/4) * original volume.
= (1/4) * 2000cum,
= 500cum.
So, Box cutting in road curst = (2000-500).
= 1500cum.

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.
