An open box is formed by cutting squares with side lengths of 3 inches from each corner of a square piece of paper. what is a si
zhannawk [14.2K]
The volume formula for a square or a rectangle, even, is V=l*w*h
Here, we are given our volume as 675, now we just have to find everything else, right?! Well, if you have a square, all 4 sides are the same exact length, so the length and the width of our formula are going to be the same so we only have to worry about finding a value for one and then use it twice. If you have a square of side length x and you cut 2 squares out of each side measuring 3 inches each, you are cutting away 6 inches. So the side now reflects a length of x - 6. Which is used for the length and the width in our formula. The height of the box will be 3 inches, or in other words, what you cut away from each corner to make a box in the first place! So our formula will look like this: 675 = (x - 6)(x - 6)3. Easiest thing to do is to divide away the 3 to get 225 = (x - 6)(x - 6). Now expand that by FOILing:
225= x^{2} -12x+36
Set it equal to 0 to solve for x, the length and width of each side by moving the 225 over to the other side:
x^{2} -12x-189=0
Now you just have to factor this.  When you do, you get x values of 21 and -9. But we all know that you cannot have a side length be a negative number so the x value is 21.  That's the side length of the original paper before you cut 6 inches away.

givi [52]
10in would be the appropriate scale factor for the drawing. 2000 is 10x200. If each inch represents 200 feet, then you would need 10 to reach the desired scale factor of the original building
