Question

Pls answer these ASAP....THANK YOU...

Answer 1

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)
