Let the length be x:- 2*(x+79) = 350 2x+158 = 350 2x = 350-158 2x = 192 x = 96 centimeters Check: 96+96+79+79 = 350 centimeters
Since it's rectangular, you simply need to multiply the length, width, and height. This will give you the volume. I guess you know what a centimeter looks like, and what 10 centimeters look like. Personally, I would probably use my hand, and check how many times the distance between my thumb and index fits on the box, since it's about 15 centimeters. Either that, or the width of my thumb, which is about 2 centimeters. But with the thumb you're going to be spending a while, so you might as well take the 1 minute and go look through your stuff to find your measuring tape. I think that approximations are very easy to do though, so you don't even need that. Just say that the box has about 50 centimeters in height, 30 centimeters in length, and 10 centimeters in width. So that gives you 15000 centimeters cube, which sounds very close to the actual volume.

Assuming your dimensions must be whole numbers! 1 x 8 x 50; 2 x 8 x 25; 5 x 8 x 10

Assuming this is a rectangular prism, the volume is height*width*length = 2(cm)*3(cm)*6(cm)= 36 cm3

The good thing about the developments of rectangular boxes is that they are still rectangular! In order to find the surface area of the paper needed to make a box, you would first need to determine the measurements of your finished box. One you have determined your length (L), width (W), and height (H), you will need to do some simple math. 2(LxW) + 2(WxH) + 2(LxH) = the area of paper that you need to make a box.
The surface area = (18 cm x 20 cm) + 4(10 cm x 20 cm) = 360cm^2 + 800 cm^2 = 1,160 cm^2
