The correct response is: The density will be smaller because the mass remains the same as the volume increases.
To understand why this is the case, we need to know the formula for density. Density is defined as the mass of an object divided by its volume. Mathematically, it can be represented as:
Density = Mass / Volume
When a larger piece of material is obtained, the volume will increase while the mass remains the same. Since density is directly proportional to mass and inversely proportional to volume, an increase in volume while keeping the mass constant will result in a decrease in density.
To calculate density, you would need to measure the mass of the material using a balance and measure the volume using various methods depending on the shape of the object. Once you have these measurements, you can then divide the mass by the volume to determine the density.
