The length of the two sides is 8 cm and the width is 4 cm. What is the circumference of the rectangle? If you put them together into a square, find the circumference of the square

The length of the two sides is 8 cm and the width is 4 cm. What is the circumference of the rectangle? If you put them together into a square, find the circumference of the square

4*8=32

There are two rectangles of equal size, 8 cm in length and 4 cm in width. Put the two rectangles together into a square, and the perimeter of the square is
How many centimeters. How to list the formula?

Perimeter of square = (4 + 4) x2 + 8x2 = 32cm

If you use eight same small cubes to form a large cube, the edge length of a small cube is 5cm, then the surface area of the large square is 5cm

A large cube is made up of eight identical small cubes
The edge length of the cube is 5cm
Large cube edge length = 10cm
The surface area of a large square
=6×10²
=600 cm²

Cut a large cube into eight small cubes of the same size. The surface area of each small cube is 18 square centimeters, and the surface area of the original cube is [] square percent

A large cube is cut into eight small cubes of the same size
Then the side length ratio is 2:1
Area ratio = 4:1
Body surface area of Zhengda square = 18 * 4 = 72 square centimeter

As shown in the figure, the surface area of the cube block is 36 square decimeters. Cut it along the dotted line into eight small cube blocks of equal volume, and the surface area increases______ Square decimeter

Cut 8 small cubes of equal volume along the dotted line, need to cut 3 times, each time cut 1, add 2 large cubes face, so a total of 3 × 2 = 6 face, is increased by 36 square decimeters. Answer: at this time, the surface area increased by 36 square decimeters. So the answer is: 36

A cube block with a surface area of 36 square decimeters is cut into eight equal cuboids, and the surface area of each cuboid is calculated

36/6=6
6/4*6=9
The surface area of each cube is 9 square decimeters

The total edge length of a cube is 36 decimeters. How many square decimeters is its surface area

A cube has 12 edges. The total length of its edges is 36 decimeters, so the edge length is 36 / 12 = 3 decimeters, and its surface area is 3 * 3 * 6 = 54 square decimeters

The surface area is 36 square decimeters of cube wood on the table, the area of wood on the table is () square decimeters

36 / 6 = 6 square decimeters

If you cut a cube with a surface area of 36 square decimeters into eight small cubes, its surface area will increase by () square decimeters

If you cut a cube with a surface area of 36 square decimeters into eight small cubes, its surface area will increase by (108) square decimeters

The two cubes with the edge length of 2 cm are put together to form a rectangle. How much is the total edge length and the surface area of the assembled rectangle reduced
What are the total length and surface area of a rectangle?

The length of the assembled rectangle is 2 * 2 = 4, the height is 2, and the width is 2
Sum = 4 * (4 + 2 + 2) = 32
Original = 2x2 * 12 = 48
Reduced by 48-32 = 16 cm
Area reduced by 2, bottom area = 2x2x2 = 8 square centimeter
