The average density of living matter on Earth's land areas is 0.10g/cm squared. What mass of living matter in kilograms would occupy an area of 0.125 ha? I think I can answer this if i knew what ha was. Any help would be appreciated.

Ha stands for hectare, which is a unit of area commonly used in agriculture and land measurement. One hectare is equal to 10,000 square meters or 0.01 square kilometers.
To calculate the mass of living matter that would occupy an area of 0.125 ha, we need to convert the given density from g/cm² to kg/m², and then multiply it by the area.
Given:
Average density = 0.10 g/cm²
Area = 0.125 ha
First, we need to convert the density from g/cm² to kg/m²:
1 g/cm² = 1000 kg/m² (since there are 1000 grams in a kilogram)
Next, we convert the area from ha to m²:
1 ha = 10,000 m²
Area = 0.125 ha × 10,000 m²/ha = 1,250 m²
Now, we can calculate the mass of living matter:
Mass = Density × Area
= 0.10 kg/m² × 1,250 m²
= 125 kg
Therefore, the mass of living matter that would occupy an area of 0.125 ha is 125 kilograms.
Certainly! "ha" stands for hectare, which is a unit of area commonly used in agriculture and land measurement. One hectare is equal to 10,000 square meters or 100 acres.
To calculate the mass of living matter, you need to multiply the density (0.10g/cm²) by the area (0.125 ha) and convert it to kilograms.
Here's the step-by-step calculation:
1. Convert the area from hectares to square meters:
0.125 ha * 10,000 m²/ha = 1,250 m²
2. Convert the area from square meters to square centimeters:
1,250 m² * 10,000 cm²/m² = 12,500,000 cm²
3. Multiply the area (in cm²) by the density (0.10 g/cm²):
12,500,000 cm² * 0.10 g/cm² = 1,250,000 g
4. Convert grams to kilograms:
1,250,000 g / 1000 = 1250 kg
Therefore, an area of 0.125 ha would contain approximately 1250 kilograms of living matter.
