ada yg tau cara no 4?

Volume balok
= P × L × T
= 15 cm × 12 cm × 9 cm
= 180 cm^2 × 9 cm
= 1.620 cm^3

Volume kubus
= S × S × S
= 7 cm × 7 cm × 7 cm
= 49 cm^2 × 7 cm
= 343 cm^3

Volume balok + Volume kubus =
1.620 cm^3 + 343 cm^3 =
1.963 cm^3 ( D)

SEMOGA MEMBANTU :)

volume balok : p x l x t = 15 x 12 x 9 = 1620
volume kubus : r x r x r = 7 x 7 x 7 =343
volume gabungan = 1620 + 343 = 1963
