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

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
