An indigenous plough has a 20cm wide furrow at the top and 10cm depth. Calculate the volume of soil handled per day of 8 hours if the speed of working is 2.5 km/hr.

1 answer

To calculate the volume of soil handled per day, we need to find the volume of soil handled per hour and then multiply it by the number of hours worked in a day.

First, let's convert the speed from km/hr to cm/hr:
2.5 km/hr = 2.5 * 1000 m/hr = 2500 m/hr
Since there are 100 cm in a meter, the speed is 2500 * 100 = 250,000 cm/hr

To find the volume of soil handled per hour, we need to find the volume of a rectangular prism, which is calculated by multiplying the length, width, and depth:

Volume of soil per hour = width * length * depth = 20 cm * 250,000 cm/hr * 10 cm = 50,000,000 cm^3/hr

Now we can calculate the volume of soil handled per day by multiplying the volume per hour by the number of hours worked in a day:

Volume per day = 50,000,000 cm^3/hr * 8 hr/day = 400,000,000 cm^3/day

Therefore, the volume of soil handled per day is 400,000,000 cm^3/day.
