Question

Beverley is building a toy boat.

If wood has a density under 1g/cm³, it will float.

She has a choice of three different pieces of wood.

Piece 1: volume = 400cm³ and mass = 450g.

Piece 2: volume = 0.02m³ and mass = 8kg

Piece 3: volume = 1000cm³ and mass = 1.03kg

Which piece of wood is the most suitable?

Answer 1

Answer:Piece 2

Explanation:

Taking out densities of piece using

Density=mass/volume(make sure u take same units for comparison)

We have,

Density of piece 1=1.125g/cm³

Density of piece 2 = 0.4g/cm³

Density of piece 3 = 1.03 g/cm³

Hence piece 2 is best for the toy
