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 :

 = pi times r times t \ = 3.14 times 7 {}^{2} times 36 \ = 3.14 times 49 times 36 \ = 5.538.96 : : : cm {}^{2}

Jawaban

=> 150cm²

Cara

=> 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
