Question

A student has an experiment for the density of solid. The block has dimension of square of the following Vernier Caliper reading. A student has an experiment for unit and conversion and tries to obtain the density of cubical solid. The cubic dimension of length is obtained by using Vernier Caliper and the mass using the electronic scale. Cubic mass is measured as 6.50 g. Read the value of the cubic length in the above Vernier caliper in the unit of cm. Find the volume of this cubical block in the unit of m Find the density of this cubical block in a unit of kg/m3

Explanation / Answer

a) value of cubic length = 2.548 cm
b) Volume = (2.548 * 10^-2)^3 = 16.542 * 10^-6 m^3
c) density = mass/ volume = (0.0065/16.542 * (10^-6)) = 392.939 Kg/m^3
