volume of room = l × b × h
= 4.5 x 4 x 3.5
= 63m³
hence air contained is 63m³.
No. of boys = 63m³/2.5m³
= 25.2
so rounding it so 25 can sit in that room.

Answer:
Volume of the room,
= length× breadth× height
= 4.5 ×4×3.5
=63m^3
If 1boy occupies space = 2.5m^3
Number of boys = 63×10/2.5
= 63× 10/25
= 25 boys
