Jawab pake cara ya makasihh
5) 1 m=100 cm
4(8+8+8)
4 x 24 =96 cm
100-96= 4 cm
7) 10 m= 1000 cm
4(20+17+13)
4 x 50 = 200cm
1000: 200= 5 kerangk
8) 1,4 m= 140 cm
4(15+13+t )=140
4(28+t )=140
112+4t=140
4t=28
t=7
9) s² x 6= 150m²
s²x6=15000m
s²=2500
s=50
7. 10 m = 1000 cm
Kerangka balok = 4P + 4L + 4T
(4×20) + (4×17) + (4×13)
200 cm
1000/200 = 5 buah B
8.-
9.Lpermukaan = 150m^2
150m^2 = r^2 x 6
r^2 = 150/6 = 25
r = 5
r kubus = 12
12 x 5 = 60 cm
