Tolong kak,gak usah pakai jalan ya ka
Jawaban:
L permukaan kubus :
= 6 x s x s
= 6 x 5 x 5
= 30 x 5
= 150 cm²
L permukaan Balok :
= 2 x ( p x l + p x t + l x t )
= 2 x ( 25 x 9 + 25 x 13 + 9 x 13 )
= 2 x (225 + 325 + 117 )
= 2 x 667
= 1.334 cm²
V Tabung :

=> Dik : s = 5cm
Dit : Lp?
Jawab :
Lp = 6 × s × s
= 6 × 5 × 5
= 150cm²
——————————————————–|
=> Dik : p = 25cm
l = 9cm
t = 13cm
Dit : Lp?
Jawab :
Lp = ( 2 × p × l) + ( 2 × p × t) + ( 2 × l × t)
= ( 2 × 25 × 9) + ( 2 × 25 × 13) + ( 2 ×9 × 13)
= 450 + 650 + 234
= 1.334cm²
———————————————————-|
=> Dik : r = 7cm
t = 36cm
Dit : V?
Jawab :
V = luas alas × tinggi
= ( 22/7 × 7 × 7 ) × 36
= 154 × 36
= 5.544cm³
