Question

A classroom is 12.5 long 6.4 metre broad and 5 metre high.How many students can it accommodate if each student needs 1.6 metre square floor area ?How many cubic metres of air will each student get? ​

Answer 1

Answer:

Length of cuboid = 12.5metres

Breadth of cuboid is 6.4 metre

Height of cuboid is 5 metre

Area of the rectangle= l×b= 12.5 *6.4 =80m²

Given :

Area covered by each student=1.6m²

Number of students classroom accommodates

= total area of the classroom divided by area each student takes

= 80 m² /1.6m² = 50

Volume of cuboid = lbh = (12.5 × 6.4×5) metres

= 12.5×6.4×5 = 400 m³

Total volume of the classroom = 400m³

Number of students is 50

So total air student gets is= 400m³/50

= 8m³
