To have a more stable treehouse, Charlie’s father decided to

Question

tie the corner posts of the house to the tree itself. He used 24
inches of rope for the first post, 20 inches on the second, 14
inches on the third and 12 inches on the fourth. He also had 15 feet of cable but did not use that. How many inches of rope were used?

Answer 1

To find the total inches of rope used, we need to add the lengths of rope used for each post:

1. First post: 24 inches
2. Second post: 20 inches
3. Third post: 14 inches
4. Fourth post: 12 inches

Now, let's add them together:

\[ 24 + 20 + 14 + 12 \]

Calculating the addition step by step:

1. \( 24 + 20 = 44 \)
2. \( 44 + 14 = 58 \)
3. \( 58 + 12 = 70 \)

Thus, the total length of rope used is

\[ \boxed{70 \text{ inches}} \]
