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..... :-)
