Question

What will be the labour charges for digging a cuboidal pit 6 mt long 5 mt broad and 4 mt deep at the rate of rupees 15 per 1000 dm cube

Answer 1

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

Answer 2

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

= 120$mt^{3}$

[ ∵ 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.
