Question

a clear plastic box has a base 10 cm square it contains water to a height of 10 cm a piece of Rock of mass 500 gram is lowered into the water And the water level Rise is 22 cm what is the volume of water displaced by the rock what is the volume of the rock calculate the density of the piece of Rock

Answer 1

A rectangular tank has a base that is 10cm by 5cm and a height of 20cm.

If the tank is half full of water, by how many cm will the water level rise if 325 cubic centimeter of water are poured into the tank?

:

let h = the height of the added water

10 * 5 * h = 325

50h = 325

h = 325/50

h = 6.5 cm the water will rise

please mark it as brainliest

Answer 2

it will displace 450 grams of water.

therefore water displcesd = volume of the object.
