Calculate the density of an object that has a mass of 1,245 kg and is shaped like a block with the following dimensions:

- Length: 2.2 m
- Width: 0.8 m
- Height: 0.2 m

Answer :

Final answer:

The density of an object with a mass of 1,245kg and dimensions 2.2m x 0.8m x 0.2m is calculated by first finding its volume (0.352 m³) and then dividing the mass by the volume, resulting in a density of 3,538.35 kg/m³.

Explanation:

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

To calculate the density of an object, you divide its mass by its volume. Given that the mass of the object is 1,245 kg and the dimensions of the block are 2.2m in length, 0.8m in width, and 0.2m in height, first calculate the volume.

The formula for the volume of a block is length × width × height, so the volume is 2.2m × 0.8m × 0.2m = 0.352m³. Then, to find the density, use the formula density = mass/volume. Thus, the density of the object is 1,245 kg / 0.352 m³ = 3,538.35 kg/m³.
