Answer 1

27). s = 20 cm
Luas permukaan = 6 x
Luas permukaan = 6 x
Luas permukaan = 6 x 400
Luas permukaan = 2.400 ... (d)

28). r = 10 cm
t = 40 cm
V = x x t
V = 3,14 x x 40
V = 3,14 x 100 x 40
V = 12.560 ... (b)

29). Bangun pertama : kubus
s = 8 cm
V =
V =
V = 512

Bangun kedua = balok
p = 20 cm
l = 8 cm
t = 9 cm
V = p x l x t
V = 20 x 9 x 8
V = 1.440

V total = 512 + 1.440
V total = 1.952 ... (b)
