Verified answer
V kubus = s³=15³
=3375 cm³
V limas =1/3 x luas alas x t
=1/3 x s² x (23-15)
=1/3 x 15² x 8
=1/3 x 225 x 8
= 1/3 x 1800
= 600 cm³
V bangun = 3375 +600
=3975 cm³
jawab.D
= s x s x s
= 15 × 15 × 15
= 3.375 cm³
volume limas persegi
= 1/3 x luas alas x t
= 1/3 x (15 × 15) x (23 - 15)
= 1/3 × 225 × 8
= 1/3 × 1.800
= 600 cm³
volume bangun
= volume kubus + volume limas persegi
= 3.375 + 600
= 3.975 cm³ (D)
