A botanist estimates the area occupied by open stomatal pores on the leaves of a plant.
| Quantity | Value |
|---|---|
| Estimated number of open stomatal pores | 3.0 million |
| Average area of one open pore | 4.0×101 μm24.0 \times 10^1\ \mu\text{m}^24.0×101 μm2 |
| Area conversion | 1 m2=1×1012 μm21\ \text{m}^2 = 1 \times 10^{12}\ \mu\text{m}^21 m2=1×1012 μm2 |
Calculate, in m2\text{m}^2m2, the combined area occupied by the open stomatal pores.
