How much wire should he buy if 2 windows are 15 ft. off ground and 2 houses are 32 ft. apart and trench is l ft. deep in order to install intercom between 2 houses?
To determine the amount of wire needed to install an intercom between the two houses, you need to calculate the total length of wire required. Here's how you can do it:
1. Calculate the distance between the two windows:
- Since there are two windows, multiply the distance between them by 2.
- In this case, the distance between the windows is given as 15 ft, so the total distance between the windows is 15 ft x 2 = 30 ft.
2. Determine the length of wire needed for the trench:
- The trench has a depth of l ft (indicated in the question), but the length is not specified. Therefore, you need this missing value to calculate the wire needed for the trench.
3. Calculate the distance between the two houses:
- The distance between the houses is given as 32 ft.
4. Calculate the total length of wire needed:
- Add up the calculations from steps 1, 2, and 3:
- Distance between the windows (30 ft)
- Length of wire for the trench (l ft)
- Distance between the houses (32 ft)
Total length of wire = 30 ft + l ft + 32 ft = 62 ft + l ft.
To determine the exact amount of wire needed, you would need to know the approximate length of the trench (l ft) mentioned in the question. Add this value to the total distance calculated (62 ft + l ft) to find the total length of wire required to install the intercom between the two houses.
