请识别以上图片的物理题，帮我生成详细的解题教学视频，最好能结合基础知识给予思路的引导---**Textual Information:** 的 水。现将一个边长为 10 cm、密度为 0.6 g/cm³ 的正方体木块缓慢放入水中,不计容器的厚度, (ρ$_{水}$ = 1.0×10³ kg/m³, g取 10 N/kg) 求: (1) 放入木块后,木块受到的浮力; (2) 放入木块后,溢出水的重力; (3) 放入木块后,容器对桌面的压强。 **Chart/Diagram Description:** * **Type:** Side view diagram illustrating a container filled with water and a wooden block. * **Main Elements:** * **Container:** Represented by vertical lines and a base. The base is resting on a surface indicated by diagonal lines. The top right corner shows a spout, indicating it's an overflow container. * **Water Level:** Indicated by shading within the container. The initial water level is labeled as 18 cm. * **Container Height:** The height of the water level is 18 cm. The height of the spout/overflow level is 20 cm. Both are relative to the base. * **Wooden Block:** A smaller block labeled "木块" (wooden block) is shown outside the container, resting on the same surface as the container. It is implied this block is to be placed in the water. * **Labels and Annotations:** * "木块" (wooden block) is labeled next to the small block. * "18cm" is labeled with a double-headed arrow indicating the initial water height. * "20cm" is labeled with a double-headed arrow indicating the height of the overflow spout from the base. * Diagonal lines represent the supporting surface/table. * **Relative Position and Direction:** The container is on the right, on a flat surface. The wooden block is on the left, on the same surface. The water is inside the container up to the 18 cm mark. The overflow spout is at the 20 cm mark.
