This is an arithmetic sequence, B
Answer:
31.6
Step-by-step explanation:
21 - 2/5 = 31.6
You have to multiply it all and get the answer
Archimedes principle comes to play in this scenario: The weight of water displaced equals the weight of the steel block.
Weight = density*volume
In other words,
Density of steel block*it volume = Density of water displaced*its volume
Therefore,
Volume of water displaced = (density of block*its volume)/Density of water = (2.5*10^3*8*10^3)/(1*10^3) = 20000 m^3 = 2*10^4 m^3
This displacement of water can be achieved by lifting the tank mechanically.
