To find the total cost of Ed's new floor, we first need to calculate the area of the dining room in square yards.
The area \( A \) of a rectangle is calculated using the formula:
\[ A = \text{length} \times \text{width} \]
In this case, both the length and width of Ed's dining room are 4 yards, so:
\[ A = 4 , \text{yards} \times 4 , \text{yards} = 16 , \text{square yards} \]
Next, we need to calculate the total cost of the new floor. The cost per square yard is $6.00, so the total cost \( C \) is calculated as follows:
\[ C = A \times \text{cost per square yard} = 16 , \text{square yards} \times 6 , \text{dollars per square yard} \]
Calculating this gives:
\[ C = 16 \times 6 = 96 , \text{dollars} \]
Therefore, the total cost for Ed's new floor will be:
\[ \boxed{96} \]
