Answer 1

Answer:

24.3 gram

Explanation:

According to Archimedes principle, buoyant force = weight of liquid displaced Density of the object floating in a liquid = density of the liquid * fraction of the object inside the liquid Mathematically represented thus: ρ(object) = ρ(water) * fraction f ρ(water) = 1 g/cc, fraction of the object inside the liquid  = 10% = 0.1 ρ(object) = 1 × ( 1 — 0.1 ) = 0.9 g/cc ρ(object) = 0.9 g/cc   To get the mass of a cube of ice, we use the formula M = ρV ρ = 0.9 g/cc , L = 3cm, V = L^3 = 3^3 = 27 cc M = 0.9 * 27 M = 24.3 g
