Volume of cuboid=l*b*h
=6*5*4=120m cube
1000dm=100mt
Rs15 per 100m then for 1m it is Rs0.15
Labour charges=120*0.15=Rs 18

The labour charges for digging a cuboidal pit is Rs. 18.
Step-by-step explanation:
Given,
Length(l) = 6 mt, breadth(b) = 5 mt and height(h) = 4 mt
To find, the labour charges for digging a cuboidal pit = ?
We know that,
The volume of cuboid = Length(l) × breadth(b) × height(h)
= 6 × 5 × 4
= 120mt^{3}
[ ∵ 1000 dm = 100 mt ]
Rs. 15 per 100 m
∴ 1 m labour charge =Rs. 0.15
The labour charges for digging a cuboidal pit
= 120 × 0.15 = Rs.18
- Thus, the labour charges for digging a cuboidal pit is Rs. 18.
