Question

The area of the four walls of a room is 300m^2

. Its length and height are 15 m and 6 m respectively. find its breadth​

Answer 1

Given, Area = 300m^2; height = 6m, length = 15m

=> Volume = area × height

=> 300 × 6 = 1800m^3

Volume of a cuboid = l × b × h

=> 1800 = 15 × 6 × b

=> 1800 = 90b

=> 1800/90 = b

=> 20 m
