To calculate the volume of the aquarium in liters, we need to multiply the length, width, and height in centimeters and then divide by 1000 to convert to liters. Volume = 120cm x 40cm x 55cm = 264,000 cm³ Converting to liters: 264,000 cm³ ÷ 1000 = 264 liters Therefore, 264 liters can fit in an aquarium with dimensions length 120cm, width 40cm, and height 55cm. **

The network cable in the wall can be replaced without opening the wall by using a technique called "fishing." This involves using a long, flexible tool such as a fish tape or wire snake to guide the new cable through the existing wall cavity. The process requires access to both ends of the wall where the cable needs to be replaced, and it may require some patience and skill to navigate the cable through the wall without causing damage. Additionally, there are specialized tools and equipment available that can make the process easier and more efficient. **
