Dibantu dong Guys... Nomor 5 sampai 7 Pake cara.... Yg jawab Gw kasih Brainliest dah

5) L = 6 x s x s
       = 6 x 7 x 7
       = 294 (b)

5. L = 6(s×s)
L = 6(7×7)
= 6 × 49
= 294 cm2
6. L = 2(pl + pt + lt)
426 = 2(12 ×9 + 12t + 9t)
213 = 108 + 21t
213 -108 = 21t
105 = 21t
5 cm = t
7. Volume air bak penuh
V = p×l×t
= 100 × 60 × 50
= 300.000 cm3

Volume air yang tingginya hanya 35
V = p×l×t
= 100 × 60 × 35
=210.000 cm3
Volume air yg tumpah = 300.000-210.000 = 90.000 cm3
