The sum of the circumference of the fourth grade math problem is 16 cm to find the area of the big square

The sum of the circumference of the fourth grade math problem is 16 cm to find the area of the big square

Because the perimeter of the square is 16 cm
So the side length is 4cm
So area = 4 * 4 = 16cm ^ 2

A square is divided into six rectangles of exactly the same size and shape (as shown in the figure). The circumference of each rectangle is 14 cm. What is the original circumference of the square?

Let the side length of the square be x cm, then the width of the small rectangle is 16x cm. According to the meaning of the title, we can get the equation: (x + 16x) × 2 = 14 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 76x × 2 = 14 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 73x = 14 & nbsp; & nbsp; & nbsp; & nbsp

How to determine the number of cube

In the three views, the main view is the figure from the front view, which can determine the number of layers and columns of the geometry; the left view is the figure from the left side of the object, which can determine the number of layers and rows of the geometry; the top view is the figure from the top view, which can determine the number of layers and rows of the geometry

Cut a cube carton along the line as shown in the figure and expand it into a plane view. The shape of the expanded view is
A. B. C. D.

As shown in the figure, it is cut along the cutting line in the right figure, the top, right and bottom are connected, the front, left and back are connected, and the bottom is connected with the back, which is the "3 3" structure of the square expansion; therefore, select: B

A cube carton can expand eleven different plans. Please draw six different plans,
