A rectangular metal slab of mass \( 33.333 g \) has its length \( 8.0 cm \), breadth \( 5.0 cm \) and thickness \( 1 mm \). The mass is measured with accuracy upto \( 1 mg \) with a sensitive balance. The length and breadth are measured with a vernier calipers having a least count of \( 0.01 cm \). The thickness is measured with a screw gauge of least count \( 0.01 mm \). Calculate the percentage accuracy in density calculated from above measurements.
