1.	Volume and Surface AreaQ12:A classroom is 10 m long, 6.4 m wide and 5 mhigh. If each student be given 1.6 m2 of the floorarea, how many students can beaccommodated in the room? How many cubicmetres of air would each student get?
Answer» Given the dimensions of classroom is 10m×6.4m×5m , area = 10*6.4 = 64m² so the volume of the class room will be = 320m³ now each student needs 1.6m² on the floor so no. of Student = room area/(Student area) = 64/1.6 = 40 Students. now volume of air for each student will be = total volume/no. of Student = 320/40 = 8m³

Answer»

Given the dimensions of classroom is 10m×6.4m×5m , area = 10*6.4 = 64m² so the volume of the class room will be = 320m³

now each student needs 1.6m² on the floor so no. of Student = room area/(Student area) = 64/1.6 = 40 Students.

now volume of air for each student will be = total volume/no. of Student = 320/40 = 8m³
