Answer 1

Verified answer

Diketahui :
panjang (p)= 45 dm
lebar(l)= 15 dm
tinggi(t)= 15 dm

ditanya : Luas permukaan(Lp)= ?

penyelesaian
Lp= 2(pl + pt + lt)
Lp= 2[(45 dm x 15 dm) + (45 dm x 15 dm) + (15 dm x 15 dm)]
Lp= 2(675 dm² + 675 dm² + 225 dm²)
Lp= 2(1.575 dm²)
Lp= 3.150 dm² →jawaban d

Answer 2

Verified answer

Lp balok
= 2 × ( p × l ) + ( p × t ) + ( l × t )
= 2 × ( 45 × 15 ) + ( 45 × 15 ) + ( 15 × 15 )
= 2 × ( 675 + 675 + 225 )
= 2 × 1575
= 3150 dm²
yang d

good luck :)
