How many trips of sand will cover an area of 2500 sqm with 750mm deep?

 To calculate how many trips of sand you need to cover an area of 2500 sqm with a depth of 750mm, we need to follow these steps:

1. Convert depth to cubic meters: The depth is currently in millimeters, but we need it in cubic meters to match the area measurement. Since there are 1000 millimeters in 1 meter, we have: 750 mm * (1 m / 1000 mm) = 0.75 m

2. Calculate the volume of sand needed: Multiply the area by the depth to get the volume of sand needed: 2500 sqm * 0.75 m = 1875 cubic meters

3. Determine the volume per trip of sand: Unfortunately, you haven't provided the size of each trip of sand. It could be a wheelbarrow, a shovelful, or a truckload, each with significantly different volumes. Please specify the volume of sand per trip to calculate the number of trips needed.

4. Divide the total volume by the volume per trip: Once you provide the volume per trip, simply divide the total volume needed (1875 cubic meters) by the volume per trip to get the number of trips.

For example, if each trip of sand is approximately 0.1 cubic meters, then you would need:

1875 cubic meters / 0.1 cubic meters/trip = 18750 trips
