Question

A cube made of very old hard wood has a mass of 45g and measures 6 cm a side will it sink or float

Answer 1

Answer:

Probably float, but then sink after a while

Explanation:

im not an expert about these topics but I think it will float for a while until the water soaks into the wood causing the wooden cube to sink. Sorry if it's wrong, just what I think

Answer 2

Answer:

The cube will float

Explanation:

Before we can decide if the cube will sink or float, we need to calculate the density of the object. We need to know how dense the object is.

Density is defined as the ratio of the mass of an object to its volume. Mathematically,

Density = mass/volume

Given mass = 45g and length of a cube = 6cm

Its volume = length × length × length = 6×6×6 = 216cm³

Density = 45/216

Density of the cube = 0.208g/cm³

The density of the cube is a low value and as such the cube will float
