Final answer:
The density of the substance is calculated by dividing the mass, 150000g, by the volume, which is 100,000 cubic meters based on the given dimensions. The calculated density is therefore 1.5g/m³.
Step-by-step explanation:
To calculate the density of a substance, you need to find the mass of the substance and its volume. The mass is given as 150000g. However, to calculate the volume, we need to interpret the dimensions given, which seem to be 20m x 10m x 500m. The volume would then be calculated by multiplying these dimensions: volume = length × width × height = 20m × 10m × 500m = 100,000m³. Once you know the volume, you can calculate the density using the formula density = mass / volume. In this case:
density = 150000g / 100,000m³ = 1.5g/m³.
