Diketahui panjang 21 cm,lebar 11 cm,tinggi 7 cm,Hitunglah luas dan volume balok

Jawaban:

Diketahui:

p = 21 cm

l = 11 cm

t = 7 cm

Ditanya:

Luas dan Volume Balok?

Jawab:

Luas Permukaan Balok

= 2 × (p × l + p × t + l × t)

= 2 × (21 × 11 + 21 × 7 + 11 × 7 cm)

= 2 × (231 + 147 + 77 cm)

= 2 × 455 cm

= 910 cm²

Volume Balok

= panjang × lebar × tinggi

= 21 cm × 11 cm × 7 cm

= 231 cm × 7 cm

= 1.617 cm³
