Lp kubus = 6s
2
= 6(10 cm)
= 6(100 cm²)
= 600 cm²

4. В. 125 cm³
Penyelesaian:

Volume kubus = s³ (5 cm) = 125 cm³

5. D. 340 cm²dan 400 cm³

Penyelesaian:
Lp balok = 2 (pl+pt + It)

= 2 ((10 cm x 8 cm) + (10 cm x 5 cm) + (8 cm x 5 cm))

= 2 (80 см² + 50 cm² + 40 cm²)
= 2 (170 cm²)

= 340 cm²

Volume balok = p x I x t
= 10 cm x 8 cm x 5 cm
= 400 cm
