It will be half the mass of the whole cube.

Well, isn't that just a lovely question? Imagine the cube as a whole, and then gently picture it divided into two equal parts. Since you're only looking at half of the cube, the mass would be half of the total mass of the entire cube. Just like painting, sometimes we need to break things down into smaller, more manageable parts to see the beauty in the whole picture.
The mass of one half of the cube would be half of the total mass of the cube, assuming the density is uniform throughout.
If pressure is applied to a cube until its volume is halved, the density will increase by a factor of 2, since density is equal to mass divided by volume. As the volume decreases by half, the mass of the cube remains the same, leading to a doubling of density.
To find the density of a cube, you would first measure the mass of the cube using a scale. Next, measure the length of one side of the cube to find its volume. Finally, you can calculate density by dividing the mass of the cube by its volume. Density = Mass/Volume.
To find the density of the cube material, divide the mass of the cube by its volume. You would first need to know the volume of the cube to calculate its density accurately. If the volume of the cube is 8cm³, then the density would be 96g/8cm³ = 12g/cm³.
The density of the floating cube is equal to the density of the fluid it is floating in. This is because the cube is in equilibrium, meaning the weight of the cube is equal to the weight of the fluid it displaces. Therefore, its density is the same as the fluid's density.
Half-life is the time taken for half of the radioactive material to decay. In the case of Thorium-234, after one half-life, half of the initial mass would remain.
