table attributes columnalign right center left columnspacing 0px end attributes row cell luas space permukaan space balok space end cell equals cell space 2 open parentheses pl plus pt plus lt close parentheses minus 1 half open parentheses pl close parentheses end cell row space equals cell 2 space open parentheses 12 cross times 6 plus 12 cross times 6 plus 6 cross times 6 close parentheses minus 1 half open parentheses 12 cross times 6 close parentheses end cell row blank equals cell 360 minus 36 end cell row blank equals cell 324 space cm squared space end cell end table

table attributes columnalign right center left columnspacing 0px end attributes row cell luas space permukaan space prisma end cell equals cell 2 l subscript alas space end subscript plus left parenthesis k subscript alas cross times t right parenthesis end cell row blank equals cell 2 left parenthesis 1 half cross times 6 cross times 6 right parenthesis space plus space open parentheses open parentheses 6 plus 6 plus 6 square root of 2 close parentheses cross times 6 close parentheses end cell row blank equals cell 36 plus open parentheses 12 plus 6 square root of 2 close parentheses 6 end cell row blank equals cell 36 plus 72 plus 36 square root of 2 end cell row blank equals cell 108 plus 36 square root of 2 cm squared end cell end tabletable attributes columnalign right center left columnspacing 0px end attributes row cell volume space balok space end cell equals cell space p cross times l cross times t end cell row blank equals cell 12 cross times 6 cross times 6 end cell row blank equals cell 432 space cm squared end cell end table

table attributes columnalign right center left columnspacing 0px end attributes row cell volume space prisma space end cell equals cell space l subscript alas space end subscript cross times t end cell row blank equals cell left parenthesis 1 half cross times a cross times t right parenthesis cross times t end cell row blank equals cell 1 half cross times 6 cross times 6 cross times 6 end cell row blank equals cell 108 space cm squared space end cell end table

jadi space luas space permukaan space dan space volume space bangun space ruang space gabungan space tersebut space yaitu space left parenthesis 432 space plus 36 square root of 2 right parenthesis cm squared dan space 540 space cm to the power of 3 space end exponent
