Q. MTK,

Hitunglah luas permukaan balok jika P = 26 l = 45 t = 37​

Penjelasan dengan langkah-langkah:

Diketahui:

p = 26

l = 45

t = 37

Ditanya:

Lp = ....?

Jawab:

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

Lp = 2 × ((26 × 45) + (26 × 37) + (45 × 37))

Lp = 2 × (1.170 + 962 + 1.665))

Lp = 2 × (2.132 + 1.665)

Lp = 2 × 3.797

Lp = 7.594 cm²
