Matematika dik: P 42,L 36 T 25 tentukan volume dan luas permukaan balok

dik: P 42,L 36 T 25 tentukan volume dan luas permukaan balok

Diketahui;

Panjang = 42

Lebar = 36

Tinggi = 25

Ditanya;

Tentukan volume dan luas permukaan balok !

Dijawab;

Volume Balok

V = p × l × t

= 42 × 36 × 25

= 1.512 × 25

= 37.800 cm³

Luas Permukaan Balok

Lp = 2 × ((p × l) + (p × t) + (l × t))

= 2 × ((42 × 36) + (42 × 25) + (36 × 25))

= 2 × (1.512 + 1.050 + 900)

= 2 × 3.462

= 6.924 cm²

#Cmiiw

Jawaban:

Volume = P × L × T

42 × 36 × 25 = 37.800

Luas permukaan balok = 2 × ( PL + PT + LT)

2 × (42×36 + 42×25 + 36×25) = 6.924
