Final answer:
To calculate the density of the box, divide its mass (2240 grams) by its volume (1120 cm³) resulting in a density of 2 g/cm³.
Step-by-step explanation:
The density of a material is defined as its mass per unit volume. To find the density of the box, you use the formula D = m/V, where D is density, m is mass, and V is volume. First, calculate the volume of the box by multiplying its dimensions (length × width × height) which is 10 cm × 8 cm × 14 cm, resulting in a volume of 1120 cm³. The mass of the box is given as 2240 grams.
Now, divide the mass by the volume to get the density: D = 2240 g / 1120 cm³, which simplifies to 2 g/cm³. Therefore, the density of the box is 2 g/cm³.
