Question

a room contains 67.5mcube of air .If its length and height are 6m and 2.5m respectively,find its breadth.
​

Answer 1

Answer:

height of the room= 2.5m

length of room =6m

volume of air in room=67.5cu m.

volume of a cubodial room= l×b×h

6×2.5×b=67.5

15.0h=67.5

h=67.5/15

h=4.5

Answer 2

SOLUTION:

Length of room (l)= 5 m

Breadth (b) = 4.5 m

and height (h) = 3 cm

∴ Volume of air it contains

l×b×h=(5×4.5×3)m³

=67.5 m³

ANSWER : 6.75m³
