The outside diameter of the igloo is 12 feet. The thickness of each block of ice that was used to construct the igloo is 1.5 fee
mojhsa [17]
The first thing we are going to do for this case is to model the igloo as a hemisphere.
 The volume of the hemisphere is:
 V = ((4/3) * (pi) * (r ^ 3)) / 2
 Where,
 r: sphere radio
 We have then that the internal diameter is:
 di = 12-1.5
 di = 10.5 feet
 So the radio is:
 r = di / 2
 r = 10.5 / 2
 r = 5.25 feet
 Substituting values:
 V = ((4/3) * (pi) * ((5.25) ^ 3)) / 2
 V = 303.1 feet ^ 3
 Answer:
 
the amount of space of the living area inside the igloo is:
 
V = 303.1 feet ^ 3
