Question

What will be the labour charge for digging a cuboidal pit 8 m long, 6 m broad and 3 m deep at the rate of Rs 20 per m^3

​

Answer 1

Heya!❤️

Solution :

Volume of pit = Length×Breadth× Height

$(8 \times 6 \times 3) { m}^{3}$

$144 { m}^{3}$

Since labour charges are at the rate of Rs 20/m^3

Total labour charges =

$(144 \times 20) = rs2880$

Answer 2

Answer:

Rs  2880.

Step-by-step explanation:

Given :

Length ( l ) = 8 m

Breadth ( b ) = 6 m

Height ( h ) = 3 m

And cost of digging is Rs 20 per $m^3$

First find the volume of Cuboidal pit

We know formula for volume of Cuboidal

$\large volume=length \times breadth \times height$

Putting values here we get

$\large \text{Volume of Cuboidal pit = 8\times6\times3 \ m^3 }\\\\\\\large \text{Volume of Cuboidal pit = 144 \ m^3 }\\\\\\\large \text{If cost of digging 1 m^3 = Rs 20}\\\\\\\large \text{So cost of digging 144 m^3 = Rs \ 20\times144 }\\\\\\\large \text{Cost of digging 144 m^3 = Rs \ 2880 }$

Thus we get answer.
