5.3

Density of a regular solid (measuring method)
1. Measure mass using a balance
2. Measure width, length and height using a reeler
3. Calculate volume (V = w x l x h)
4. Calculate density ((rho) = m/v)

1. m = 580.4 g

2. w = 5 cm; l = 5 cm; h = 2 cm
3. V = w x l x h = 5 x 5 x 2 = 50 cm^3
4. ρ = m/V = 580.4/50 = 11.608 g/cm^3
