tolong jawab dong semuanya ya

11.p×l×t
=15 cm ×12 cm ×10 cm
=c.1800cm3

13.d.2 (pl+pt+lt)

14.L=2 (7×5)+(7×6)+(5×6)
=2 (35+42+30)
=2 × 107
=d.214m2

Maaf no 10,12,DAN 15 gk saya jawab.

semoga bermanfaat :)

maaf kalau salah :)

10) V = r³
1.000 cm³ = r³
r = ³√1.000
r = 10 cm
Lp = 6 × r²
= 6 × 10 × 10
= 600 cm² ( D )

11) V = p × l × t
= 15 × 12 × 10
= 1.800 cm³

12) V = p × l × t
480 = 8 × 5 × t
480 = 40 × t
t = 480 ÷ 40
t = 12 cm ( C )

13) Lp = 2 × ( pl + pt + lt ) ( D )

14) Lp = 2 × ( pl + pt + lt )
= 2 × ( 7•5 + 7•6 + 5•6 )
= 2 × ( 35 + 42 + 30 )
= 2 × 107
= 214 cm²

15) Lk = 4 × ( p + l + t )
= 4 × ( 1,5 m + 50 cm + 2 m )
= 4 × ( 1,5 m + 0,5 m + 2 m )
= 4 × 4 m
= 16 m ( B )
