On the road, I saw that in the "one large and four small" project, Uncle Huang planted Moso bamboo in a wasteland with a length of 500 meters and a width of 300 meters. About 500 plants were planted per hectare. How many plants were planted in total?
路上看到"一大四小"工程中，黄叔叔在长500米，宽300米的荒地种上了毛竹，每公顷约种500株，一共种了多少株？
<gadget id="calculator">300 / 10_000</gadget>
<output>3/100 = around 0.03</output>

<gadget id="calculator">500 * (3/100) * 500</gadget>
<output>7_500</output>

<result>7_500</result>
