Problema Solution
You are going to make a box out of cardboard. The box needs to measure 10 cm by 5 cm by 5 cm; 10% of the final product will be wasted in the cutting process. How much cardboard do you need?
Answer provided by our tutors
The area of the cardboard - 10% wasted in cutting = The area of the box (we assume the box is closed)
Let 'x' represent the area of the cardboard before the cutting.
x - 0.10x = 2(10*5 + 5*5 + 10*5)
