what will be the labour charges for digging a cubodial pit 6m long, 5m broad and 4m deep at the rate of 15 per 1000dm^3
Answers
Given data : A cuboidal pit 6 m long, 5 m broad and 4m deep at the rate of 15 units per 1000 dm³.
To find : What will be the labour charges for digging a cuboidal pit ?
Solution : Here, a/ct to given data;
- Length of the pit = 6 m
- Breadth of the pit = 5 m
- Depth/Height of the pit = 4 m
Firstly we have to find out the volume of the cuboidal pit, so we use formula of cuboid;
➜ Volume of the pit = length * breadth * height
➜ Volume of the pit = 6 * 5 * 4
➜ Volume of the pit = 30 * 4
➜ Volume of the pit = 120 m³
Hence, volume of the pit is 120 m³.
Here,a/c to given data, charges of digging is at the rate of 15 unit per 1000 dm³.
We know that,
➜ 1 dm³ = 0.001 m³ or 1 m³ = 1000 dm³
Hence,
➜ 1000 dm³ = 1 m³
Hence, the charges of digging is at the rate of 15 unit per m³. {15 unit per 1 m³}
➜ Charges of the digging = Volume of the pit * digging charge per m³
➜ Charges of the digging = 120 * 15
➜ Charges of the digging = 1800 units
Answer : Hence, the labour charges for digging a cuboidal pit is 1800 units.
