Question

How would you calculate density for a cubic solid ?

Answer 1

You are given the mass of the metal block, but you must calculate its volume using the measurements of the given dimensions. For a rectangular solid, volume = length x width x height; therefore, the volume of the block is (3 cm)(5 cm)(4 cm) or 60 cubic centimeters. The density is 14 g/60 cc or 0.23 g/cc.

Answer 2

First find the volume. The expression for regular shape like cubic solid is v=length x width x height
Then find the mass of the cube by using a scale. Finally use the expression to find the density.
D= mass divided by volume (D= mass/volume )
