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.
The given cuboidal pit has its length (l) as 8m, width (b) as 6m, and depth (h) as 3m.
Volume of pit = l × b × h
= (8 × 6 × 3) m3
= 144 m3
Cost of digging per m3 volume = Rs 30
Cost of digging 144 m3 volume = Rs (144 × 30) = Rs. 4320
