Step-by-step explanation:
The lengths of the sides of the original box are
Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:
We also know that the area is
And the area can be written as product of length and width, therefore:
So we find:
Solving for x,
Which has two solutions:

x = 2 cm
So, the length of the new sides are
Answer:
x = or 5.83
Step-by-step explanation:
A² + B² = C²
3² + 5² = x²
9 + 25 = x²
34 = x²
= x
or
5.83 = x
