A team of engineering students is testing their newly designed raft in the pool where the diving team practices.
The raft must hold a 730 kg steel cube with edges of length 45.0 cm without sinking. Assume the 3 density of
water in the pool is 1000 kg m . The students use a crane to gently place the cube on the raft but accidentally
place it off center. The cube remains on the raft for a few moments and then the raft tilts, causing the cube to
slide off and sink to the bottom of the pool. The raft remains floating in the pool. In a coherent paragraph-length
response, indicate whether the water level in the pool when the cube is on the bottom of the pool is higher than,
lower than, or the same as when the cube is on the raft, and explain your reasoning. For both cases, assume that
there is no motion of the water.

When the cube is on the raft, the water displaced is equal to the weight of the cube and raft. When the cube is in the water, the water displaced is equal to the weight of the raft, plus the volume of the cube. Since the volume of the cube is less than the volume of water needed to displace its weight, the water level is lower.

When the cube is at the bottom of the pool the water level in the pool is lower. The water level is lower due to the buoyancy force.

What is buoyancy force?

The weight of a partially or totally submerged item is pushed upward by a fluid. Pressure rises with depth in a column of fluid due to the weight of the overlying fluid.

As a result, the bottom of a fluid column has a higher pressure than the top.

When the cube is on the raft, the amount of water displaced is equal to the cube's and raft's combined weight.

When the cube is submerged, the amount of water displaced is equal to the raft's weight plus the cube's volume.

The water level is lower because the volume of the cube is smaller than the amount of water required to displace its weight.

Hence the water level is lower.
