Question

a rectangular room thrice as long as it is broad is 5m high and it contains 60 cubic metres of air. find its length and breadth

Answer 1

Answer:

Length = 6m and Breadth = 2m

Step-by-step explanation:

Let Breadth of rectangle room be x.

Then length = 3x

Now,

➡️Volume of room= volume of air = 60 m^3

Volume of room = length ☓ Breadth ☓ height

(room is cuboid)

60 = x ☓ 3x ☓ 5

12 = 3x^2

x^2 = 4

x = 2 m

Breadth = x = 2m

Length = 3x = 3 ☓ 2 m = 6m
