Xiao Ming fills a rectangular glass container with a bottom of 30cm×30cm, and pours part of the water into a square iron bucket. When the square iron bucket is filled with water, the water surface in the rectangular container drops by 20cm, then is the square iron bucket longer than 25cm? Xiao Ming filled a 30 cm×30 cm rectangular glass container with water. He poured a portion of the water into a square iron bucket. When the square iron bucket was filled with water, the water in the rectangular container dropped by 20 cm. Was the square iron bucket longer than 25 cm?
Let the prism length be x
Then x3=30×30×20=18000
X≈26.2m
26.2M >25m
Over.
Can you give me five points? Thanks!

- 5. 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.
