Two identical blocks of ice float in water as shown. Then:
A) block A displaces a greater volume of water since the pressure acts on a smaller bottom area
B) block B displaces a greater volume of water since the pressure is less on its bottom
C) the two blocks displace equal volumes of water since they have the same weight
D) block A displaces a greater volume of water since its submerged end is lower in the water
E) Block B displaces a greater volume of water since its submerged end has a greater area

Quizplus · Accepted Answer

The amount of water displaced by an object is equal to the weight of the object. Since the two blocks of ice are identical in weight, they will displace equal volumes of water. The other answer choices are either incorrect or do not affect the amount of water displaced.
