Bantuuuu yaaaaaaa! :)

Penjelasan dengan langkah-langkah:

volume = volume1 + volume 2

$= (p times l times t ) + (p times l times t) \ = (9 times 3 times 11) + (5 times 11 times 5) \ = 297 + 275 \ = 572 \$

luas permukaan = (2(pl + pt + lt)+2(pl + pt + lt)

$(2(9 times 11 + 9 times 3 + 3 times 11) + (2(5 times 11 + 5 times 5 + 11 times 5) \ = (2(99 + 27 + 33)) + (2(55 + 25 + 55) \ = (2 times 159) + (2 times 135) \ = 318 + 270 \ = 588$
