Answer 1

Answer:

4.05 cm

Step-by-step explanation:

As volume of cube = $(side)^3$

Extra Volume added = Volume of cube given = $9^3$=729 $cm^3$

As We know that , Volume = (Base Area) * (Height),

Extra Volume Added= (Base Area)* (Rise of Water Level)

$729 = (15)(12)h$,where h is the rise of water level.

$h = \frac{729}{180}$

h=4.05 cm
