Maths Question

[MegaOctane12]

Need help quick. I'm buying some mylar soon and I want to buy enough so I coat the small grow space without going over the top.

Height 78 3/4 inches (2meters)
Width 33.4 inches (0.85 meters)
Length 19.5 inches (0.50 meters)

Mylar is sold in 1m x 1.4m strips. How many mylar strips will I need to buy without going over. Really need help terrible at maths.:confused:

My advice, don't buy it! I'm quoting "The Cannibis Grow Bible." It says Mylar is the second best thing to reflect light. The best way to get maximum reflection is to paint everything flat white. You will find it cheaper and probably easier and faster. I even spray painted the black hanging light sockets in my space. Have fun;)

I'm not sure, but tell me if this looks right to ya.

m2 is meters squared

Back wall = 1.7m2
Front wall = 1.7m2
left side = 1m2
right side = 1 m2

Total surface area = 5.4m2

mylar sheets = 1.4m2

5.4m2/1.4m2 = ~4 sheets

That will help you decide if you want to use mylar or not.

Sorry lady but I think the bible is off the mark on mylar if they say flat paint is better....it's all in the math.

Well I now got the mylar so thanks everyone who gave input. Painting a closet isn't really an option because that would mark it for life, so I can never use it again. Also i've been told that mylar reflects more than white paint, its very hard to transport though.
