RUMUS
volume balok = P x L x T
= 15 x 11 x 9
= 1.485cm²
jadiin jawaban terbaik yaah.. :))
semoga membantu :)
Jawaban:
Luas permukaan = 2 × ( p × ℓ + p × t + ℓ × t )
= 2 × ( 15 × 11 + 15 × 9 + 11 × 9 )
= 2 × ( 165 + 135 + 99 )
= 2 × ( 399 )
= 798 cm

Jawaban:
Diketahui : P = 15 cm
: L = 11 cm
: T = 9 cm
Luas permukaan = 2 × ( p × ℓ + p × t + ℓ × t )
= 2 × ( 15 × 11 + 15 × 9 + 11 × 9 )
= 2 × ( 165 + 135 + 99 )
= 2 × ( 399 )
= 798 cm
