Answer: 0.439488 N
Step-by-step explanation:The apparent weight of the metal is computed as
apparent weight = weight - weight of the displaced fluid
To compute the weight of the metal, we use the following formula:

where



Note that the volume is unknown but we can compute this because the metal is a cube with edge = 2 cm = 0.02 m. So, the volume of the metal is given by

Thus, the weight of the metal is computed as

Next, we compute the displaced weight or buoyancy, which has the following formula

where

Note that the displaced volume is equal to the volume of the submerged metal. Since the metal has a volume of

, the displaced volume is

.
Thus, the weight of the displaced fluid is calculated as

Therefore,
apparent weight of the metal
= weight of the metal - weight of the displaced fluid
= 0.517968 N - 0.07848 N
apparent weight of the metal = 0.439488 N
