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

### Instruction:
Cooper is building a brick fence around all four sides of his property.  Each of the four walls of his fence is 20 bricks long, 5 bricks high, and 2 bricks deep.  How many bricks does Cooper need to complete his fence?

### Response:
 Safu moja ya kila ukuta inahitaji matofali 20 * safu 5 = <<20*5=100>>100 ya matofali.
Kwa kuwa ukuta una unene wa matofali 2, atahitaji matofali 100 * 2 = <<100*2=200>>200 kwa kila ukuta.
Kukamilisha uzio, atahitaji jumla ya matofali 200 * ukuta 4 = <<200*4=800>>800.
