volume bangun ruang tersebut adalah

V1 : 10 × 10 × 8
= 100 × 8
= 800 cm kubik

V2 : 7 × 8 × 16
= 56 × 16
= 896 cm kubik

Volume bangun ruang = V1 + V2
= 800 + 896
= 1696 cm kubik

Volume balok1= p x l x t
= 10 x 10 x 8
= 800 cm^3

Volume balok2 = p x l x t
= 16 x 8 x 7
= 896 cm^3

Volume bangun tersebut = Vbalok1 + Vbalok2
= 800 cm^3 + 896 cm^3 = 1.696 cm^3
