LSA of cube = 4 x a = 4 x 10 = 40 sq. cm
LSA of cuboid = 2h (l+b) = 2x 8 ( 12.5 + 10)
= 16 ( 22.5) = 360sq. Cm
Cuboid has greater surface area by 320sq.cm
TSA of cube = 6xa = 6 x 10 = 60 sq. cm
TSA of cuboid = 2(lb + bh + lh)
= 2( 12.5 x 10 + 10 x 8 + 12.5 x 8)
= 2 ( 125 + 80 + 100)
= 2 x 305
= 610 sq cm
Cube has less TSA by 550sq cm
