In an experiment with light, Rodney used 6 square polarized filters, 3 in. on a side. What was the total surface area of the filters? Count one face only for each filter.
6 * 3^2 = ?
To determine the total surface area of the 6 square polarized filters, we need to calculate the surface area of a single filter and then multiply it by the number of filters.
The formula to calculate the surface area of a square is given by: A = s^2, where A is the surface area and s is the length of one side of the square.
Given that each filter has a side length of 3 inches, we can substitute this value into the formula:
A = 3^2
= 9 square inches
Since each filter has two faces, we need to multiply the surface area by 2:
Total surface area of a single filter = 2 * 9 = 18 square inches
To find the total surface area of all 6 filters, we multiply the surface area of a single filter by the number of filters:
Total surface area = 18 * 6 = 108 square inches
Therefore, the total surface area of the 6 square polarized filters used by Rodney is 108 square inches.
To find the total surface area of the filters, we need to calculate the area of each individual filter and then multiply it by the total number of filters.
The area of a square is calculated by multiplying the length of one side by itself. In this case, the length of one side of the square filter is given as 3 inches.
So, the area of each square filter is 3 inches * 3 inches = 9 square inches.
Since Rodney used 6 filters, we multiply the area of one filter (9 square inches) by the total number of filters (6) to get the total surface area.
Therefore, the total surface area of the filters is 9 square inches * 6 = 54 square inches.
