# Homework Help: Calculus question

I know this is simple, but I don't understand the English of this problem:

An open box, no more than 5 cm in height, is to be formed by cutting four identical squares from the corners of a sheet of metal 25 cm by 32 cm, and folding up the metal to form sides. The capacity of the box must be 1575 cm^3. What is the side length of the squares removed?

Anyone that cares to help or explain this problem will be welcome!

Well I found the equation to be (32-2x)(25-2x)x=1575
where x = 3.5
But still, if anyone can explain this problem in a more simple format, then I can ensure myself won't be stuck in one of these word problems, it really took me too long to figure this out. Thanks in advance!

ok, makes sense now- you are cutting squares on the corner
edges of the sheet. Well, you solved the problem , what exactly
do you need help on? The problem is pretty simple once
we understand the instruction. A picture is worth a thousand
words...

I need help on solving word problems fast. I can solve an algebra mathematical problem like 10X faster than I can solve word problems. Any tips?

Well, the key thing is to understand the problem.
I screwed up on your question because I missed
the keyword "corners", reading too rapidly. I thought
the question asked one to cut the metal into 4
squares, lol.

So, read the problems slowly and draw a cartoon diagram
of it, making sure you clearly see what you are solving.
