The rate has been measured in terms of per Metre square meaning we will use the surface area. That is the total surface area covered by the pit.
Since the pit is an open cuboid then the area covered is the total surface area of a cuboid.
Total S. A=(8×6)+(2×6×3)+(2×8×3)=132m2
The total cost=30×132=3960
Rs3960

Answer:
Rs 4320
Step-by-step explanation:
l = 8 m, b = 6 m, h = 3 m
volume of Cuboidal pit = l ^ b^ h
= ( 8^ 6^ 3) m3
= 144 m3
cost of digging 1 m3 = Rs 30
cost of 144 m3 = Rs ( 144^ 30)
= Rs 4320
:': cost of digging the pit is Rs 4320
