Hiii friend,


Volume of cube = 125

a³ = 125

a = ✓125 = 11.18 cm

WHEN THREE CUBES ARE JOIN END TO END THEN THE LENGTH, BREADTH AND HEIGHT OF THE RESULTING CUBOID IS THAT,

LENGTH = 11.18 + 11.18 = 22.36 CM

BREADTH = 11.18 CM

HEIGHT = 11.18

THEREFORE,

TSA OF CUBOID = 2(LB + BH + HL)

= 2(22.36×11.18 + 11.18 × 11.18 + 11.18×22.36)

= 2(249.9848 + 124.9924 + 249.9848)

= 2(624.962) = 1249.925 CM²

HENCE,

THE TSA OF RESULTING CUBOID = 1249.825 CM²

HOPE IT WILL HELP YOU..... :-)
