Density = (mass) / (volume) <== MEMORIZE THIS !
1). Mass = 50 g. Volume = 100 cm³. Density = (mass) / (volume)
===================================
2). Volume = (length) ·(width) ·(height) = (4cm) ·(4cm) ·(4cm) = 64 cm³
Mass = 672 g. Density = (mass) / (volume)
===================================
3). Volume = (length) ·(width) ·(height)
Length = 1 meter = 100 cm
Width = 10 cm = 10 cm
Height = 22 mm = 2.2 cm
Volume = (100 cm) (10 cm) (2.2 cm) = 2,200 cm³
Mass = 42,460 g
Density = (mass) / (volume)
