if 4 is at the bottom of the rectangle box what would u use to find the diagonal cb
To find the diagonal cb of the rectangle box, you can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides.
In the rectangle box, the diagonal cb forms the hypotenuse of a right triangle with sides of length 4 (bottom of the rectangle) and the length of the rectangle. Let's assume the length of the rectangle is x.
Using the Pythagorean theorem, we have:
(4)^2 + x^2 = (diagonal cb)^2
16 + x^2 = (diagonal cb)^2
Now you can solve for the value of the diagonal cb.
