Q. A rectangular metal slab of mass

33.333 g

has its length 8.0 cm, breadth 5.0 cm and thickness 1mm. The mass is measured with accuracy up to 1 mg with a sensitive balance. The length and breadth are measured with vernier calipers having the least count of 0.01 cm. The thickness is measured with a screw gauge of least count 0.01mm. The percentage accuracy in density calculated from the above measurements is :
