Different scales, uses and construction methods. Reservoirs and reservoirs are both artificial bodies of water used to store water resources. The differences are:
1. Scale: Reservoirs are generally larger than reservoirs and can store more water resources.
2. Purpose: Reservoirs are generally used for large-scale water conservation projects such as irrigation, power generation and water supply, while reservoirs are generally used for water conservation projects small-scale water, agricultural irrigation, urban projects. water supply, etc.
3. Construction method: Reservoirs are usually built by damming rivers to form an artificial lake, while reservoirs are usually built in valleys or low-lying areas, and the resourcesWater is stored through dikes or retaining walls. . It should be noted that the construction of reservoirs and reservoirs should take into account environmental protection and ecological balance in order to avoid adverse effects on the surrounding ecological environment. Additionally, geological conditions, hydrological conditions and other factors must be considered during the construction process to ensure the safety and reliability of the project.
1)
20×10×1.5×1
=200×1.5
=300 (ton)
Answer: This tank can store up to 300 tons of water
2)
20×10+20×1.5×2+10 ×1.5×2
=200+60+30
=290 (square meters)
6×290=1740 (kilograms)
Answer: A total of cement should be used 1740kg
