Q34.A 400 g solid cube having an edge of length 10 cm floats in water. How much volume of the cube is outside the water ? (Given : density of water = 1000 kg m−3 ) (1) 1400 cm3 (2) 600 cm3 (3) 4000 cm3 (4) 400 cm3
What This Question Tests
This question is a straightforward application of Archimedes' principle and the concept of floatation to determine the submerged volume of a floating object.
Concepts Tested
Formulas Used
F_buoyant = V_submerged * ρ_liquid * g
V_submerged * ρ_liquid = V_total * ρ_object (for floating)
