Penjelasan dengan langkah-langkah:
1) 15³ - 7³ = 3.000 + a
3.375 - 343 = 3.000 + a
3.032 = 3.000 + a
a = 3.032 - 3.000
a = 32
2) ³√1.728 x ³√125 = 12 x 5 = 60
3) V = V. Kubus + (V. Balok Besar - V. Balok Kecil)
= (s³) + ((p1 x l1 x t1) - (p2 x l2 x t2))
= (6³) + ((9 x 6 x 4) - (3 x 4 x 1))
= 216 + (216 - 12)
= 216 + 204
= 420 cm³
4) V. Balok = p x l x t
= 32 x 16 x 8
= 4.096 cm³
V. Balok = V. Kubus
V. Kubus = s³
4.096 = s³
s = ³√4.096
s = 16 cm
5) V = p x l x t
680 = 17 x l x 5
680 = 85 x l
l = 680/85
l = 8 cm
