Jawaban:
1. A. Volume = 343 cm3
Luas = 294 cm2
B. Volume = 3375 cm3
Luas = 1350 cm2
2. Volume = 192 cm3
Luas = 188 cm2
Penjelasan dengan langkah-langkah:
1.
A. Panjang sisi 7 cm
Volume = s x s x s = 7 x 7 x 7 = 343 cm3
Luas = 6 x s x s = 6 x 7 x 7 = 294 cm2
B. Panjang sisi 15 cm
Volume = s x s x s = 15 x 15 x 15 = 3375 cm3
Luas = 6 x s x s = 6 x 15 x 15 = 1350 cm2
2.
p = 8 cm
l = 4 cm
t = 6 cm
Volume = p x l x t = 8 x 4 x 6 = 192 cm3
Luas = 2(pl + pt + lt) = 2((8 x 4) + (8 x 6) + (4 x 6))
Luas = 2(32 + 48 + 24)
Luas = 2(94)
