A student is given an iron cube of side 1 cm, a measuring cylinder of range 100 mL and least count 1 mL, and a spring balance of range 100g wt and least count 1g wt. He can use these to measure :
(1) both the mass and the volume of the given iron cube
(2) neither the mass nor the volume of the given iron cube
(3) only the mass of the given iron cube but not its volume
(4) only the volume of the given iron cube but not its mass

Solution

The student can measure the mass of the cube by using spring balance. Also, he can measure the volume of the cube by immersing the whole spring balance system with the attached cube, inside the measuring cylinder. The volume of the water displaced will be equal to the volume of the body.

Hence, the correct answer is option 1.
