Here is a very simple math problem that is beyond my skills. →[More:]

We need to wrap a queen-sized mattress in plastic sheeting. I need to know what size roll of poly sheeting to buy.

The dimensions of a queen-sized bed are 60" x 80". Let's assume it's, what, 8" tall?

So, in feet, what how much plastic do I need?

(Seriously, I came up with a measurement that roughly equals the square footage of my house, so I'm coming to y'all for help.)

60+60+16=136 with no extra, wrapping around side to side

80+80+16=176 with no extra, wrapping around top to bottom

If the rolls are 60 inches wide (five feet), you need at least 136 inch (12 feet) long roll

If the rolls are 80 inches wide (seven feet), you need at least 176 inch (15 feet) long roll

If the rolls are narrower than five feet, I dunno.

I think I have that right in my own convoluted way.

hm, I just came up with 26.25 square feet, but I'd add an extra 6" or so inches for overlap.

and I think the issue (which I vaguely recall from having an architect as a mother) is that to calculate square feet, you need to work in linear feet (and fractions thereof), not linear inches.

this from someone who failed 4th grade arithmetic, not to mention Algebra 1 twice, so take my advise with a grain of salt.

wiggle wrong is what I have branded my lovemaking technique.

*reviews* GOD DAMMIT this is why I suck at math... fucking volume geometry. Of course you said you gotta wrap it not merely cover it so you multiply the area by two and a bit to account for the sides.
