In an experiment on determining density of a rectangular block, the dimensions of the block are mesured with vernier callipers `(V.C = 0.01 cm)` and its mass is measured with a beam balance `(L.C. = 0.1 g)`. The measured values are :
Mass`(m) = 39.3` g
Length`(l) = 5.12` cm
Breadth`(b) = 2.56` cm
Thickness`(t)=0.37` cm
Calculate density of the block with permissible limits of error.
