Finding the Dimensions of a BoxDate: 10/21/2001 at 18:26:20 From: Kaila Subject: Finding the demensions of a box You want to construct a cardboard box from a cardboard strip that is 8 inches wide. The dimensions of the box are 8 inches by 8 inches by 4 inches. How long does the strip need to be? I tried to find the answer by saying 8x8+4+4 and I got 40, but none of my friends or family can help me and I'm not sure if I'm right.

So we can draw those sides: +---------+ | 8 | | 8| length * width | | | | +---------+ +---------+ | 8 | | 8| length * width | | | | +---------+ +---------+ | 8 | | 4| length * height +---------+ +---------+ | 8 | | 4| length * height +---------+ +---------+ | 8 | | 4| width * height +---------+ +---------+ | 8 | | 4| width * height +---------+ If you put all the sides together, you can make a strip of cardboard 8 inches wide... and how long? - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
