Luas permukaan balok dengan ukuran 12cm X 10cm X 8cm adalah.... A. 592cm B. 360cm C. 296cm D. 256cm Mohon bantuan & caranya yaa :)
marfaaudilla19luas permukaan =( ( p x l ) + ( p x t ) + ( l x t ) )x 2 =( ( 12 x 10 ) + ( 12 x 8 ) + ( 10 x 8 ) )x 2 =( 120 + 96 + 80 )x 2 = 296 x 2 = 592 cm² ( a )

Diketahui : p = 12 cm l = 10 cm t = 8 cm Ditanyakan : LP balok...?? Jawab : LP balok = 2 ( pl + pt + lt ) LP balok = 2 ( 12.10 + 12.8 + 10.8 ) LP balok = 2 ( 120 + 96 + 80 ) LP balok = 2 ( 296 cm^2 ) LP balok = 592 cm^2 ( A ) Jawabannya A....
=( ( 12 x 10 ) + ( 12 x 8 ) + ( 10 x 8 ) )x 2
=( 120 + 96 + 80 )x 2
= 296 x 2
= 592 cm² ( a )
p = 12 cm
l = 10 cm
t = 8 cm
Ditanyakan : LP balok...??
Jawab :
LP balok = 2 ( pl + pt + lt )
LP balok = 2 ( 12.10 + 12.8 + 10.8 )
LP balok = 2 ( 120 + 96 + 80 )
LP balok = 2 ( 296 cm^2 )
LP balok = 592 cm^2 ( A )
Jawabannya A....
