Answer 1

1) V balok + V limas
= p.l.t + 1/3.s².t
= 16.16.5 + 1/3.16².6
= 1280 + 512
= 1792 cm kubik


2) V 1/2 bola + V kerucut
= 1/2.4/3.phi.r^3 + 1/3.phi.r².t
= 2/3.3,14.1,5.1,5.1,5 + 1/3.3,14.1,5.1,5.2
= 7,065 + 4,71
= 11,775 cm kubik

Answer 2

1.
volume = volume balok + volume limas
             = (S x S x T) + ( 1/3 x luas alas x TL)
             = ( 16 x 16 x  5 ) + ( 1/3 x 16 x 16 x 6)
             = 1792

2.
volume = volume 1/2 bola + volume kerucut
             = 1/2 x 4/3 x π x r³ + (1/3 x π x r² x t)
             = 1/3 π r² ( 2 r +  t)
             = 1/3 x 3,14 x 1,5² ( 2x 1,5 +  2)
             = 11,775
