a railing for a deck requires pieces of cedar 4 ft 8 in., 11 ft 7 in., and 9 ft 3 in long. what is the total length of material that is needed?
Let's add these lengths together. First lets add the feet -- 4 + 11 + 9 = 24 feet.
Now add the inches. 8 + 7 + 3 = 18
So -- we need 24 feet plus 18 inches.
Since 18 inches is more than a foot, you'll need to convert your answer to get feet plus the number of inches (under 1 foot).

To find the total length of material needed for the deck railing, we need to add together the lengths of the cedar pieces provided.
First, let's convert the measurements to a consistent unit. In this case, let's convert everything to inches.
The measurements given are:
- 4 ft 8 in,
- 11 ft 7 in,
- 9 ft 3 in.
Converting feet to inches, we know that 1 foot is equal to 12 inches. So we have:
- 4 ft 8 in = (4 * 12) + 8 in = 48 + 8 = 56 in
- 11 ft 7 in = (11 * 12) + 7 in = 132 + 7 = 139 in
- 9 ft 3 in = (9 * 12) + 3 in = 108 + 3 = 111 in
Now, let's add up the converted measurements:
Total length = 56 in + 139 in + 111 in = 306 in
Therefore, the total length of material needed for the deck railing is 306 inches.
