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

### Instruction:
 Cooper anajenga uzio wa matofali kuzunguka pande zote nne za mali yake. Kila ukuta wa uzio wake una urefu wa matofali 20, kimo cha matofali 5, na kina cha matofali 2. Matofali mangapi anahitaji Cooper kukamilisha uzio wake?


### 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.
