Answer 2

5) L = s²
= 16²
= 256 cm² (D)

6) s = K : 4
= 156 : 4
= 39 cm (A)

7) s = √L
= √576
= 24 cm (C)

8) V.kubus = s x s x s
= 18 x 18 x 18
= 5832 cm kubik (C)

9) s = akar pangkat tiga dr V
= akar pangkat tiga dr 729
s = 9 cm (A)

10) K = 2 x ( p+l)
= 2 x (34+56)
= 2 x 90
= 180 cm (B)

11) K = 2 x (p+l)
240 = 2 x (70+l)
240:2 = 70+l
120 = 70+l
l = 120-70
l = 50 cm (D)

12) L = a x t
= 34 x 9
= 306 cm² (tdk ad pilihan jwbnnya)

13) L = 1/2 x (jumlah sisi sejajar) x t
= 1/2 x (46+34) x 27
= 1/2 x 80 x 27
= 1.080 cm² (A)

14) V.balok = p x l x t
= 50 x 35 x 40
= 70.000 cm kubik
= 70 Liter (B)

15) L = 1/2 x a x t
= 1/2 x 24 x 32
= 384 cm² (C)
