mohon di bantu ya kak, pake cara jangan lupa, makasi yyaaa​

Answer 1

1. LP kubus = 6 x s

= 6 x 15

=90 cm²

2.LP kubus=6 x s

2.400=6 x s

2.400:6 =s

400 =s

3.LP balok= 2 ((p x l)+(p x t)+(l x t))

= 2 ((10x6)+(10x4)(6x4))

= 2 (60+40+24)

=2(124)

= 248 cm²

4. LP balok tanpa tutup=(p x l)+2(lxt)+2(pxt)

1.104 =(24x18) +2(18xt)+2(24xt)

1.104 =432 + 36t +48t

1.104 =432 + 84t

1.104 - 432 = 84t

672= 84t

672:84= t

8=t
