Tolong jwb no 22-27 kak​

Jawaban:

24. C

25. B

26. B

27. B

Penjelasan dengan langkah-langkah:

Nomor 24.

L = s²

144 = s²

s = akar 144

s = 12

V = s³

= 12³

= 1728 cm³

Nomor 25.

La = p x l

90 = 15 × l

l = 90/15

l = 6

Lp = 2(p x l + p x t + l x t)

= 2(15 × 6 + 15 × 4 + 6 × 4)

= 2(90 + 60 + 24)

= 2(174)

= 348 cm²

Nomor 26.

Lp = 2(p x l + p x t + l x t)

376 = 2(10 x 8 + 10 x t + 8 x t)

376/2 = 80 + 10t + 8t

188 = 80 + 18t

18t = 188 – 80

t = 108/18

t = 6

V = p x l x t

= 10 x 8 x 6

= 480 cm³

Nomor 27.

T = 10

a = 12

t = 9

c² = 12² + 9²

c² = 144 + 81

c² = 225

c = akar 225

c = 15

Lp = 2 × La + Ka × T

= 2 × a × t + (a + c + t) × T

= 2 × ½ × 12 × 9 + (12 + 15 + 9) × 10

= 108 + 360

= 468 cm²
