$colorbox{red}{no.1}$

= 15³ + 12³
= (15×15×15) + (12×12×12)
= 3.375 + 1.728
= 5.103 ✓

$colorbox{red}{no.2}$

$volume = panjang : times : lebar : times : tinggi \ = 15 : times : 8 : times : 10 \ = 120 : times : 10 \ color{red}{ = 1.200 : {cm}^{3} }$

$colorbox{red}{no.3}$

= √36
= √6
= 6 ✓

$colorbox{red}{no.4}$

= 190 + 256 – 87 ÷ 2
= 190 + 256 – 43,5
= 446 – 43,5
= 402,5 ✓

✠Pertanyaan✎

1. 15³ + 12³ = …?

2. Diketahui :

p = 15 cm

l = 8 cm

t = 10 cm

Hitunglah volume balok tersebut!

3. √36 =

4. 190 + 256 – 87 ÷ 2 = …?

ᬁPenyelesaian﴿

➜ Nomor 1.

15³ + 12³

= ( 15 × 15 × 15 ) + ( 12 × 12 × 12 )

= 3.375 + 1.728

$= sf red{5.103}$

➜ Nomor 2.

V = P × L × T

= 15 × 8 × 10

$= sf blue{1.200 : : cm {}^{3}}$

➜ Nomor 3.

√36

= √6²

$= sf orange{6 }$

➜ Nomor 4.

190 + 256 – 87 ÷ 2

= 190 + 256 – 43,5

= 446 – 43,5

$= sf{ purple{402.5}}$
