24. LUAS PERMUKAAN BALOK
= 2 × ( PL + PT + LT)
= 2 × ( 15 × 7 ) + ( 15 × 9 ) + ( 7 × 9 )
= 2 × ( 105 + 135 + 63 )
= 2 × 303
= 606 Cm². ( B).
25. VOLUME BANGUN RUANG
= ½ × AC × BC × CF
= ½ × 16 × 12 × 24
= 8 × 12 × 24
= 96 × 24
= 2.304 Cm³. ( D).

Penjelasan dengan langkah-langkah:
24) B
Lp = 2 x (15 x 7 + 15 x 9 + 7 x 9)
= 2 x (105 + 135 + 63)
= 2 x 303
= 606 cm²
25) D
Volume = 16 x 12/2 x 24
= 384 x 6
