tolong dong jawabannya 1 sampai 2

1. V1 = 3×3×3 = 27
V2 = 9×9×9 = 729
perbandingan 27:729 = 1:27

2. 5×4x + 4×4x + 3×4x = 240
20x + 16x + 12x = 240
48x = 240
x = 5
p = 5× 5 = 25
l = 4× 5 = 20
t = 3 × 5 = 15
V = 25×20×15 = 7500cm^3

3.V = 6cm×6cm×6cm= 216cm^3
diperbesar 4/3 kali
(4/3×6)^3 = 512cm^3

4.26 + 18 + 14 = 58×4 = 232cm

5.4(a) + 4(a-3) + 4(5) =88
4a + 4a-12 + 20 = 88
8a + 8 = 88
8a = 80
a = 10
p = 10
l = 10-3 = 7
t = 5

V = 10×7×5 = 350cm^3


maaf kalau salah
