Question 1001894: Here is my question:
The circular base of a cylindrical water tank has an area of 1 metre squared. A solid cube with edges of length 20cm is dropped beneath the surface of the water. What is the resulting increase in the height of the water level in cm?
Thanks!

The circular base of a cylindrical water tank has an area of 1 metre squared.
A solid cube with edges of length 20cm is dropped beneath the surface of the water.
:
Find the volume of the solid cube 20^3 = 8000 cu/cm
we assume it will displace 8000 cu/cm of water.
:
What is the resulting increase in the height of the water level in cm?
let h = the height increase of the water in this cylinder (in cm)
Change 1 sq/meter to sq/cm 100^2 = 10000 sq/cm
:
The area of the base (in cm) * height = 8000
10000h = 8000\
h = 8000/10000
h = .8 cm increase in water level
