Pembahasan Soal:

Diketahui:

Balok biru muda dengan ukuran begin mathsize 14px style 5 space cm cross times 5 space cm cross times 11 space cm end style.

Balok biru tua dengan ukuran begin mathsize 14px style 3 space cm cross times 3 space cm cross times 11 space cm end style.

  • Volume balok biru muda

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell straight V subscript straight b. space muda end subscript end cell equals cell straight p cross times straight l cross times straight t end cell row blank equals cell 5 space cm cross times 5 space cm cross times 11 space cm end cell row blank equals cell 275 space cm cubed end cell end table end style

  • Volume balok biru tua

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell straight V subscript straight b. space tua end subscript end cell equals cell straight p cross times straight l cross times straight t end cell row blank equals cell 3 space cm cross times 3 space cm cross times 11 space cm end cell row blank equals cell 99 space cm cubed end cell end table end style

  • Volume balok gabungan

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell straight V space gabungan end cell equals cell straight V subscript straight b. space muda end subscript plus straight V subscript straight b comma space tua end subscript end cell row blank equals cell 275 space cm cubed plus 99 space cm cubed end cell row blank equals cell 374 space cm cubed end cell end table end style
