As shown in the figure, it is a shape diagram of a three-dimensional figure seen from three different directions. The three-dimensional figure is composed of some identical small cubes. The number of these identical small cubes is () A. 4B. 5C. 6D. 7
From the known top view, we can get that the three-dimensional figure is composed of five stacks of small cubes. From the front view, we can see that there is only one small cube in the first stack. From the side view, we can see that there is only one small cube in the third and fifth stacks, and there are only two small cubes in the second and fourth stacks. Therefore, there are seven of these same small cubes, so the answer is: 7
A cube is a figure composed of six identical squares, right? Why?
Wrong
For example: in a plane, a figure composed of six identical squares is not a cube
A cube is a figure surrounded by identical squares
The lengths of the opposite edges of a cuboid are equal. The lengths of the edges of a cube are equal. For a cube with an edge length of 3cm, its total edge lengths are [] cm, and the area of a surface is [] square cm. The total edge lengths of a cube with an edge length of 60m are [] cm
A cube is a six sided figure surrounded by six identical squares
The lengths of the opposite edges of cuboid [4] are equal, and the lengths of the edges of cube [12] are equal. For a cube whose edges are 3cm long, the total length of its edges is [36] cm, and the area of a face is [9] square cm. The total length of its edges is a cube whose edges are 60 decimeters long, and the total length of its edges is [5 decimeters]
A cube, also called (), is a three-dimensional figure surrounded by () squares
A cube, also called a hexahedron, is a three-dimensional figure surrounded by six identical squares

I don't know anything about three views! I mean from the main view, left view, top view, or from the main view, top view, left view and it gives you two views. How do you judge the other view and know the maximum and minimum number of cubes? (well, it seems a little cumbersome ~)
