A truck whose bed is 2.5m long, 1.5m wide, and 1m high is delivering sand to a construction site. How many trips must the truck make to deliver 7? cubic meters of sand? Plese explain your answer.
7/(2.5*1.5*1) = 1.866
so, the truck must make 2 trips, since 7m^3 is more than one load (3.75 m^3)
To find out how many trips the truck must make to deliver 7 cubic meters of sand, we need to calculate the volume of sand the truck can carry per trip and then divide 7 cubic meters by that volume.
The volume of the truck's bed can be calculated by multiplying its length, width, and height. So, the volume of the truck's bed is:
Volume = length × width × height
= 2.5m × 1.5m × 1m
= 3.75 cubic meters
Therefore, the truck can carry 3.75 cubic meters of sand in one trip.
To determine the number of trips required to deliver 7 cubic meters of sand, we need to divide the total volume of sand by the volume capacity of the truck per trip:
Number of trips = Total volume of sand ÷ Volume capacity per trip
= 7 cubic meters ÷ 3.75 cubic meters per trip
We can divide these numbers to get the answer:
Number of trips = 7 ÷ 3.75
≈ 1.87
Since we cannot have fractions of trips, we need to round up to the nearest whole number. Therefore, the truck must make 2 trips to deliver 7 cubic meters of sand.
