Question 1144223
A large vase has a square base of side length 6cm, and flat sides sloping outwards at an angle of 120° with the base. Water is flowing in at 12cm^3/s. Find, correct to three significant figures, the rate at which the height of water is rising when the water has been flowing in for 3 seconds.

Can you provide the formula for the volume as a function of the depth?
I can do it, but it's not educational for me.
