Question

Find how many students fall short to arrange 1800 students into equal number of rows
and column.
​

Answer 1

Step-by-step explanation:

1800÷2

=900

900÷2

=450

=450÷2

=225

=225÷3

=75

=75÷3

=25

=25÷5

=5

=5÷5

=1

1800=2×2×3×5

=60

therefore 60 rows is the answer

Answer 2

Answer:

36 students fall short

Step-by-step explanation:

To arrange maximum no. of students in equal no. of rows and columns we have to calculate it's nearest square

therefore, nearest squares of 1800 is 42 and 43

42*42<1800<43*43

1764<1800<1849

but we need nearest square smaller than 1800 .

Hence, 42 is the no. of rows and columns and

1764 students were required

Students who fall short to arrange = 1800 - 1764

= 36
