The volume of water in the iron bucket is the volume of water in the original container of 20cm. If you ask for the side length of the bottom of the bucket, is there a problem? At most, you can find out the rectangular area of the bottom.
The bottom is square, and the volume of water is the volume of iron bucket filled with water,30x30x20=18000cm3
The square area of the bottom of the iron drum is 18000/10=1800cm2
The side length is 30√2
A rectangular glass container with a square bottom surface and a bottom edge of 30CM is filled with water. Now pour some water into a square bottom surface. A rectangular glass container with a square bottom surface and a bottom edge of 30CM is filled with water. Now, pour some water into an iron bucket with a square bottom surface and a height of 10CM. When the iron bucket is filled with water, the sleep in the container drops by 20cm. How long is the bottom edge?
If the container is lowered by 20cm, the volume poured out can be calculated as 20×30×30=18000cm3
The iron bottom area is 18000÷10=1800
Bottom side length 2=1800
Bottom edge length=30 pcs.2

- 8. When the atmospheric pressure is low in summer, the professional fish farmers need to add oxygen to the fish pond to prevent the death of fish from hypoxia. Xiao Ming designed an automatic oxygenation system. He modified the mercury barometer in the laboratory. A copper wire is sealed at the left top of the barometer, and a copper wire is fixed at the right opening, as shown in the figure. The mercury surface on the left of the barometer is above the vacuum. When the left mercury surface drops, the right mercury surface will rise. If the external atmospheric pressure is lower than the pressure generated by the 74cm high mercury column, the mercury column will connect the copper wires on both sides, so that the control circuit of the electromagnetic relay will form a path, and the electromagnet will absorb the armature. When the working circuit is connected, the oxygenation pump (AC motor) works automatically. (1) The copper conductor on the right side of the barometer shall be extended vertically downward to the right center of ______cm. Please draw it in the figure at the same time. (2) Please connect the circuit directly in the drawing according to the requirements.
