Final answer:
To find the total number of solar panels on the farm, multiply the number of rows by the panels per row to get the total per array, then multiply that by the number of arrays. There are 5,040 solar panels on the solar farm.
Step-by-step explanation:
A solar farm has 6 rectangular arrays of solar panels. Each array has 105 rows with 8 panels in each row. To find out how many solar panels are on the solar farm, we need to perform a multiplication operation.
First, we calculate the number of panels in one array by multiplying the number of rows by the number of panels per row:
105 rows × 8 panels/row = 840 panels/array.
Next, we multiply the number of panels in one array by the total number of arrays:
840 panels/array × 6 arrays = 5,040 panels.
Therefore, there are a total of 5,040 solar panels on the solar farm.
