Answer 1

Verified answer

Penjelasan dengan langkah-langkah:

Luas permukaan balok = 2 × (pl + lt + pt)

dik p = 25 dm

l = 12 dm

t = 15 dm

maka:

Lp = 2 × ((25×12)+(12×15)+(25+15))

= 2 × ( 300 + 180 + 375)

= 2 × 885

= 1. 710 dm²

semoga membantu

Answer 2

Jawaban:

luas permukaan balok=2×(pl+pt+lt)

=2×(25×12) +(25×15)+(12×15)

=2×(300+375+180)

=2×855

=1710cm²
