Anonymous users2024-02-11With a piece of paper with a length of 26 and width 18 to form a cylinder, the side area of this cylinder is 26x18 = 468cm can be enclosed into 2 cylinders of different shapes, the side area of the cylinder is equal to 468cm (1) cylinder: the circumference is 26cm, the height is 18cm (2) cylinder: the circumference is 18cm, the height is 26cm.
Handsome dude, can you please write down the age - reply to me. The largest size of this circle is that its diameter is the width of a rectangle. So the area is equal to the square of r.
The radius is 9 so area = 81 = square centimeters. Take a picture directly, and then** an app called Xuebao, and then upload it to solve it quickly Isn't this a math problem? 26x18x25 = 11700 (cubic centimeters.)
11700 50 = 234 (cubic centimeters). 26 14 18 6552(cm3) 6552cm3 So that's it, by the way, what grade are you in? 26 18-2 2 4 = 452 square centimeters Volume = (26-4) (18-4) 2 = 616 cubic centimeters This box uses 452 square centimeters of iron sheet, and the volume is 616 cubic centimeters.
Elementary school students, right? Is it an Olympiad.
Title? Problem solving ideas: 20 books, the total volume is certain, to make the wrapping paper the most economical, it is necessary to make the surface area after packaging.
How to minimize the surface area after packaging? The reason is: when the volume is constant, the surface area of the sphere is the smallest; If it has to be a cube (i.e. a cuboid or a cube), make 3 edges.
It's very simple, first calculate the volume of a book. Multiply by 80! Long multiplication.
Width by height. It is about a sector with an angle between the outer diameter and the inner diameter. I used it, and the thickness of the material is different, slightly different.
