Answer:
The density of the swimmer is 0.0342 lbm/in3.
This value makes sense as the density of the body is very similar to the water.
Explanation:
If the swimmers is floating, the weight of the swimmer must be equal to the upward buoyant force.
We can express the weight force as the product of density and volume of the swimmer.
Then
[tex]\rho_{swimmer}*V_{swimmer}=\rho_{water}*V_{water_displaced}\\\\
\rho_{swimmer}*V_{swimmer}=\rho_{water}*0.95**V_{swimmer}\\\\
\rho_{swimmer}=0.95*\rho_{water}\\\\
\rho_{swimmer}=0.95*0.036 lbm/in3\\\\
\rho_{swimmer}=0.0342lbm/in3[/tex]
It makes sense as the density of the body is very similar to the water.
