Answer :
Yes, because the six buses could carry 252 people in total and there are 221 student.
After calculating, we find that all 221 students can be transported to the picnic since the 6 available buses can accommodate a total of 252 students.
To determine if all 221 students can go by bus to the picnic using 6 buses, each with a capacity of 42 students, you would multiply the number of buses by their capacity and compare that to the total number of students:
6 buses*42 students/bus = 252 available spaces
Since 252 spaces are available and there are only 221 students, it is clear that all students can be accommodated on the buses, with some extra space.
