In the bottom half of the igloo, there are 10 rows / 2 = <<10/2=5>>5 rows of bricks of snow.
So in the bottom half of the igloo, there are 5 rows * 12 bricks of snow in each row = <<5*12=60>>60 bricks of snow.
In the top half of the igloo, there are 5 rows * 8 bricks of snow in each row = <<5*8=40>>40 bricks of snow.
There is therefore a total of 60 + 40 = <<60+40=100>>100 bricks of snow in the igloo.
