tolong dibantu kakak kakak (pakai caranya)

1.
a) 6.s.s = 6.3.3 = 54 cm2
b) 6.s.s = 6.5.5 = 150 cm2
c) 6.s.s = 6.2,5.2,5 = 37,5 dm2

2. 96cm2 216mm2 37,5 dm2
Luas Permukaan = LP
a)
LP = 6.s.s
96 = 6.s2
s2 = 96/6
s2 = 16 cm
s = √16 cm
s = 4 cm

b)
LP = 6.s2
216 = 6.s2
s2 = 216/6
s2 = 36 mm
s = √36 mm
s = 6 mm

c)
LP = 6.s2
37,5 = 6.s2
s2 = 37,5/6
s2 = 6,25 dm
s = √6,25 dm
s = 2,5 dm

Maaf kalo ada yg salah^^
