Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Libby is building an igloo in her backyard using bricks of snow. She builds her igloo in rows, using a total of 10 rows of bricks of snow. The bottom half of the igloo has 12 bricks of snow in each row while the top half of the igloo has 8 bricks of snow in each row. How many bricks of snow did Libby use for her igloo?

### Response:
 Katika nusu ya chini ya igloo, kuna mistari 10 / 2 = <<10/2=5>>5 ya matofali ya theluji.
Hivyo katika nusu ya chini ya igloo, kuna mistari 5 * 12 ya matofali ya theluji katika kila mstari = <<5*12=60>>60 ya theluji.
Katika nusu ya juu ya igloo, kuna mistari 5 * 8 ya matofali ya theluji katika kila mstari = <<5*8=40>>40 ya theluji.
Hivyo kuna jumla ya matofali 60 + 40 = <<60+40=100>>100 ya theluji katika igloo.
