If I need to reupholster a couch that is 6 feet long and 54 inches tall and the fabric is 4.99 a yard how much fabric would I need?

Your question is impossible to answer.

It ignores the depth of the seat.

the depth of the couch is 12 inches

6 feet = 2 yards

54 inches = 1.5 yards
12 inches = 0.3 yards

(2 * 1.5) + (2 * 0.3) = ?

That gives you the square yards. You still need to know the width of the fabric to know how much to purchase.

To calculate the amount of fabric you would need to reupholster a couch, you need to determine the total area to be covered. In this case, you have the length and height of the couch.

First, you need to convert the measurements to the same unit. Let's convert the height from inches to feet. Since there are 12 inches in a foot, dividing 54 inches by 12 will give you 4.5 feet.

Now, you can calculate the total area of the couch by multiplying the length and height together. In this case, the total area would be 6 feet * 4.5 feet, which equals 27 square feet.

Next, convert this measurement into the number of yards required. Since there are 9 square feet in a square yard (3 feet * 3 feet), divide the total area (27 square feet) by 9. This would give you 3 square yards of fabric needed.

Finally, you mentioned that the fabric is priced at $4.99 per yard. Multiply the total number of yards needed (3) by the price per yard ($4.99). This gives you the total cost of fabric required, which would be $14.97.

So, you would need approximately 3 square yards of fabric to reupholster the couch, which would cost around $14.97.
