Question

A) A 4.00 cm x 4.00 cm x 4.00 cm cube of density 920 kg/m3 is floating at rest at the top of a beaker of cross sectional area 100 cm2 with 500 mL of water in it (1 mL of water has a volume of 1 cm3 or 1x10-6 m3 ). 500 mL of oil of density 900 kg/m3 is added to the top of the beaker, and the cube is observed to float completely submerged, unevenly straddling the boundary between the oil and water. i. [4 pts] Draw a picture showing the beaker, layers of oil and water, and the block. Also draw a Free Body Diagram of the block ii. [2 pts] Using your Free Body Diagram, find the total Buoyant Force on the block. Explain your answer. iii. [5 pts] Using Archimedes’ principle, determine the volume of water displaced by the block and the volume of oil displaced by the block.

I do not understand how to do this problem specially the last part. would you please give me a detail answers so I can learn the learn how to do it myself. thank you so much
