Question

the length of a hall is 24 metre and the width is 16 the sum of the areas of the floor and the flat roof is equal to the area of four walls find the height of hall and the volume of air contained in the world

Answer 1

Answer:

3686 m³

Step-by-step explanation:

length = 24

width = 16

area of floor and roof = 2× 24× 16

                                   =768 m²

2(24×h+16×h)=768

2(40h)=768

40h =384

h= 9.6 m

volume=24×16×9.6

           = 3686.4 m³

Answer 2

Answer:

3686.4m3

Step-by-step explanation:

l=24m

b=16m

2lb=2h(l+b)(given)

2*24*16=2h(24+16)

768=80h

h=9.6

volume of air = volume of room

=lbh

=24*16*9.6

=3686.4m3
