Answer:
0.0025g/cm³
Explanation:
Given parameters:
Mass of the brown sugar = 12.9g
dimension of the sugar = 8cm
unknown:
density of the sugar = ?
Solution
Density is defined as the mass per unit volume of a substance. The expression is given below:
Density = 
We know the mass of the substance but the volume is unknown:
Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³
Density of the brown sugar =
= 0.0025g/cm³
