Object a has a length of 4 cm, a width of 3 cm, and a height of 1 cm. object b is dropped into a graduated cylinder. it displaces 15 ml of water. the volume of object a is: greater than the volume of object b less than the volume of object b equal to the volume of object b

its less than object b

volume = l x w x h

4x3x1 = 12cm

the object = how much water it displaced

15ml

cm and ml are the same thing so

12<15

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
