Penjelasan dengan langkah-langkah:
a. V = .... ?
V balok = p × l × t
= 25 × 15 × 13
= 375 × 13
= 4.875 cm³
V kubus = s³
= 13 × 13 × 13
= 2.197 cm³
V = V balok + V kubus
= 4.875 + 2.197
= 7.072 cm³
b. Lp = .... ?
Lp balok = 2 × (pl + pt + lt)
= 2 × ((25 × 15) + (25 × 13) + (15 × 13))
= 2 × (375 + 325 + 195)
= 2 × (700 + 195)
= 2 × (895)
= 1.790 cm²
Lp kubus = 6 × s²
= 6 × 13 × 13
= 78 × 13
= 1.014 cm²
Lp = Lp balok + Lp kubus
= 1.790 + 1.014
= 2.804 cm²
