The length of a room is double its breath. Its height is 5m the area of four walls ( including the door and windows) is 210sq m. Find its volume solve this sum

6 answers

width --- x m
length --- 2x m
height ---- 5 m

total surface area of the 4 walls
= (5)(2x) + (5)(x) + (5)(2x) + (5)(x)
= 30x

But in your un-punctuated sentence you say that this is 210 m^2
30x = 210
x = 7

so the room is 7m by 14m by 5 m
for a volume of 490 m^3

"Find its volume solve this sum" ----> I hope your text did not ask the question in that way.

Thanks for giving such a great answer

That's not good

Better
