since edge of aluminium cube is 0.18
so, [0.18×0.18×0.18]
=0.0058
now
volume =Mass/density
0.0058=mass/2.70
mass=0.0058×2.70
=0.015
so, [0.18×0.18×0.18]
=0.0058
now
volume =Mass/density
0.0058=mass/2.70
mass=0.0058×2.70
=0.015

Density = 2.70 g /cm³
Edge of the cube , a = 0.18 cm
Volume of a cube = a³
∴Volume of the aluminum cube = (0.18)³
= 0.005832 cm³
Density = Mass ÷ Volume
∴ Mass = Density × Volume
= 2.70 g /cm³ × 0.005832 cm³
= 0.015746 grams
