Final answer:
The correct answer is option A) 128 cubic feet. The number of cubic feet in a cord of wood is calculated by dividing the total volume of wood sold by the number of cords sold.
Step-by-step explanation:
To calculate the number of cubic feet in a cord, we need to use the total volume of wood sold and divide it by the number of cords sold. In this case, 4,480 cubic feet of wood divided by 35 cords equals 128 cubic feet per cord, making option A the correct answer.
The formula for this calculation is:
Total Cubic Feet of Wood ÷ Number of Cords Sold = Cubic Feet per Cord
If the lumberyard sold 4,480 cubic feet of wood and they sold 35 cords, the calculation is:
4,480 cubic feet ÷ 35 cords = 128 cubic feet per cord
This means that each cord of wood contains 128 cubic feet, making option A the correct answer.
