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? thank you to all answer

First, you need to organize your problem.

What is the area of cardboard needed is the question being asked.

So x = the area of cardboard needed.

How much will be wasted? Why 10% of x, right. So how much will be used in making the box? 90% perhaps?.

In that case .9x = how much is used up in making a box of the dimensions specified.

The trick is to start by translating the problem into the symbols of algebra.

Assuming box has no top: surface area = 200 sq.cm. (two 5by5 ends, three 5by10 for 2 sides and bottom).
If 10% of that is wasted, then 20 sq.cm. is wasted.
Between you and me, kind of a silly problem :idea:

timothyhag52,

it would be 10% of the \(\displaystyle original \ product \ (original \ amount \ of \ cardboard) \ that \ will \ be \ wasted.\)

Or, the final product represents what is left after 10% (of the original product)
is wasted in the cutting process.

And, are you meaning a rectangular-shaped piece of cardboard for the beginning
amount of cardboard?
