Iceberg

What is the surface area of 50 cm iceberg (in the shape of a cuboid) that can carry a man with luggage with a total weight of 120 kg?

Correct result:

S =  3 m2

Solution:

h=50 cm→ m=50/100  m=0.5 m m=120 kg  ρ1=1000 kg/m3 ρ2=920 kg/m3  ρ=ρ1−ρ2=1000−920=80 kg/m3  m=ρV  V=m/ρ=120/80=32=1.5 m3 V=Sh  S=V/h=1.5/0.5=3 m2
