mbernyciak 1)
Pp=6×a²
150=6×a²/6
a²=25
a=√25 a=5
V=a³ V=5³=125(cm)³

2)
V=a×a×b
80=4×4×b
80=16×b
80=16b/16 b=5(cm)
Pc=2×(4×5+4×5+4+4)
Pc=2×(20+20+16)
Pc=2×56=112(cm²)

Kajtuś13 1.Pp = 6*a²
150 = 6*a² /6
a² = 25
a = √25
a = 5
V = a³
V = 5³ = 125(cm)³

2.V=a*b*c
80cm[sześciennych] = 4*4*c
80=16*c /16
c=5
Pc = 2Pp + Ppb
Pc = 2*4*4+4*5
Pc= 2*16+20
Pc=32+20
Pc=52
