Answer 4

Mass of the marble is 12 grams. When dipped in water it displaced water and volume of displaced water = volume of marble =50-40 = 10ml
density = mass/volume = 12gm/10ml = 1.2gm/mL

Answer 5

Yup its 1.2 g/ml... in the diagram at the left, you had not dipped the ball in the cylinder... at that time water in the cylinder was at 40 ml... when you dipped the ball into the volume.... water displaced from 40 to 50.... so we have to find volume here that increased due to ball... for that we apply the formula..... final volume - initial volume = 50ml - 40 ml = 10 ml..... now we have to apply the formula Densty = mass/ volume.. mass of the ball is 12gm... and volume we find is 10 gm... so we have Density = 12g/10ml which is equal to 1.2 g/ml....

Answer 6

marble mass is 12gm..the marble ..therefore..dip it in a measuring cylinder..or a graduated cylinder..which shows the amount of liquid it has inside it..the cylinder says its highest consistency is 100 ml.it raises from 10 ml,50 ml etc.and these values indicate how much water or other liquid that looks like water can be poured inside.and the mili-litre value is not applicable for height length.it signifies the amount of liquid.the density..it has nothing to do with the marble so far..8)
