Plywood is sold in rectangle sheets 4 feet wide and 8 feet long.

[DBee]

How many 4x8 sheets of plywood are needed to completely cover a rectangle shaped floor measuring 16 feet by 12 feet.

six

calculus optimization word problem. no thanks i just had a test on this ****.

Srs?

lol not really. its 6. did it in my head

[JoshSP1985]

six did in head 8 feet pieces will cover one side of the rectangle and extend 4 feet you need to travel 12 feet total so 3x2

[Rhev]

the answer is six. I work at home depot. come at me bros

16 x 12 = 192
4 x 8 = 32

192 / 32 = 6

Done.

lol thats not the true optimization of materials though.

you would set the constraint as 192ft^2= lw

isolate one of the variables then plug it back into the equation and get the first derivative for the true answer OP.

16 x 12 = 192 sq ft
1 plywood= 32 sq ft
192 /32 = 6

i dont do math either....so am i right?

I was going to answer OP. But then i read^^^^^^
Now i just have a headache.. perhaps a beer is in order now.

its an even six tho

i really think he is making the prob harder than it is......we dont need no stinking equations
