Finding a measurement?
Question:I'm making a box but it's not going to be square. The top of this box is going to have a 45 degree drop off. If the flat of this box is 11" and then it has a 3.5" 45 degree drop what would be the bottom measurement for the sides of this box?
Answers:
I get 12.75 inches, too.
Use the pythagrean theroem. If the long side of a right trianghle is C, then Asq + Bsq = Csq. So if you imagine the 3.5 drop off as the long side of a triangle with a 90 degree angle opposite, you can figure out the length of the bottom side. In your case, since the drop off is 45 degrees, the length and height A and B, are going to be equal.
So the number you are looking for is the square root of 3.5, or 1.75 + 11 inches = 12.75
18" (11 + 3.5 + 3.5)
14.5 if both sides taper 12.75 if only one side tapers at 45 degrees distance is half the length so 3.5 is 1.75
71/2in
Use Pythagoras' Theory,
11x11-3.5x3.5
121-11.25
Sq Root =10.476"
