Answer:

The total cost of laying the concrete is Rs. 25,20,000

Step-by-step explanation:

Given:

Length of pit  (l)= 180 m.

Width of pit  (b )= 70 m.

Depth of pit  ( h )= 40 m.

Volume of pit = volume of cuboid = lbh

                                                         = 180 × 70 × 40 = 5,04,000 cu .m.

Cost of laying concrete inside the pit = RS.5 per cu. m.

Total cost of laying the concrete = Cost per cu. m. × total volume

                                                      = 5 × 5,04,000 = Rs.25,20,000
