Question

You have a heavy piece of wood that measures 2 cm x 10 cm x 5 cm.You find its mass is 89 g. Will this piece of wood float?

Answer 1

volume = 2*10*5

            =100 cm³

density = mass/ volume

            =89/100

            =0.89 g/cm³

density of wood is less than 1

thus wood will float in water.
