This question involves the concepts of th magnetic field and current.
The magnetic field created by the current at the house is "6.75 x 10⁻⁷ T".
<h3>Magnetic Field</h3>
The magnetic field created by a current carrying wire can be given by the following formula:
where,
- B = magnetic field = ?
= permeabiliy of free space =4π x 10⁻⁷- I = current = 152 A
- r = distance = 45 m
B = 6.75 x 10⁻⁷ T

Answer:
Explanation:
Given:
The area of the house 
The height of the house 
We need to find the volume of a typical house.
Solution:
We find the volume of the house by multiplying the area of the house and height of the house.
Area and height of the house are known, so we substitute these value in above equation.
Now we convert the unit from feet to meter.
Divide the volume by 3.2808 for 
Therefore, the volume of the house is
