volume bangun tersebut adalah...cm3 a.37.500 b.42.000 C.57.000 d. 84.000

V Balok + V prisma segitiga
( p × l × t ) + ( 1/2 × a × t × T )
( 40 × 30 × 25 ) + ( 1/2 × 30 × 20 × 40 )
30.000 + 12.000
42.000 cm3

== Jawaban ==
L1 =
p . l . t
40 . 30 . 25
30.000

L2 =
½ . a . t . T
½ . 30 . 20 . 40
12.000

L1 + L2 =
30.000 + 12.000
= 42.000 cm²

Semoga membantu
