Is the room made of rectangular floor and rectangular walls?can you determine the height of a room if you know the square footage of the walls and SF of the floor? Assume the ceiling height is the same in all of the room.

With or without doors/windows/skylights?

Please show us what you have tried and

Do you know each wall's area, or only the total of all four walls? Five numbers (actually three) should be sufficient to determine the three dimensions of the room, but two would not be.can you determine the height of a room if you know the square footage of the walls and SF of the floor? Assume the ceiling height is the same in all of the room.

Thank you very much for the reply. All I have is the SF of the Floor (Ceiling, which is the same as the floor) and the total SF of the Walls. I am really trying to determine the cubic feet of the room, which is the SF of the Floors X the height, however, I don't know the height. Therefore, I was trying to determine the height, so that I could multiply it times the SF of the Floors. So, I assume if I only have the two numbers (SF of Walls and SF of Floor), that I cannot determine the height?Do you know each wall's area, or only the total of all four walls?

I appreciate your time and for answering my post.

What about Windows and doors ? How are those accounTed for in the sq.footage?Just to add another note, here is exactly what I have. I am trying to determine cubic feet of the room.

If you only had the two areas, that would not be enough. For example, if you only had floor = 333.73 and walls = 558.88 (and assuming those are not reduced by doors and windows, and everything is rectangular), then you can say only that LW=333.73 and 2(L+W)H = 558.88, which couldn't be solved for each variable. (Note that wall area equals floor perimeter times height, because it's the sum of each side times the height.)Thank you very much for the reply.

Yes, I think the 16 was left over from an earlier error and I forgot to correct it.Thank you very much. It appears that you solved it. However, wouldn't the cubic feet be the SF of the Floor (L * W) * H, or 333.73 * 8 = 2,669.84, not 333.73 * 16
