luas permukaan gabungan bangun ruang tersebut adalah
Jawaban:
Luas gabungan
=Lbalok + Lkubus
=2×(pl+pt+lt) + 4×s×s
=2×(56×16+56×28+16×28) + 4×16×16
=2×(896 + 1.568 + 448) + 1.024
=2×2.912 + 1.024
=5.824 + 1.024
=6.848 cm²
jadi jawaban: b. 6.848 cm²

ANSWER
luas permukaan = 16 × 16 × 4
= 1024
luas = ( 28 × 28 × 56 ) + 56 × 16 + 16 × 44 + 28 × 16 + 40 × 16
= 3136 + 896 + 704 + 448 + 640
= 6848 cm² ( B )
