Question 1153754
.


Problem 1)


<pre>
After cutting the squares and then bending, the dimensions of the base of the box will be  (40-2x) cm and (30-2x) cm,

where x is the side of the square.


It is the first and the major step in the solution.


Then the area of the base of the box is the product  (40-2x)*(30-2x).

It should be equal to 900 cm^2, which gives you the equation


    (40-2x)*(30-2x) = 900.


Next, you should simplify it; reach a quadratic equation in standard form, simplify and solve.
