Question 1:
A cube of edge 15 cm is immersed completely in a rectangular vessel containing water. If the dimensions of the base of the vessel are 20 cm × 15 cm, find the rise in water level.
A. 10.25 cm
B. 11.25 cm
Feedback Increase in volume = Volume of the cube = (15 × 15 × 15) cm³
Raise in water level = (Voulme/Area) = (15 x 15 x 15/ 20 x 15)cm = 11.25 cm
C. 12.25 cm
D. 13.25 cm
