Question

Find the cost of digging a cuboidal pit 8 m long, 6 m broad and 3 m deep at the rate of Rs. 30 per m3 .

Answer 1

Given length of the cuboidal Pit (l) = 8 m

Width (b) =6 m

Depth (h) =3 m

Volume of cuboid pit =l x b x h = (8 x 6 x 3) m3

= 144 m3

Cost of digging 1 m3 = Rs.30

Cost of digging 144 m3 = 144 (Rs.30) = Rs. 4320.
