Step-by-step explanation:
Hello Dear
______________________________________________________________
When edge of 10 cm Cube join together the dimensions of formed cuboid are
@Length (l) = 20 cm
@Breadth(b)=10 cm
@Height (h)=10 cm
______________________________________________________________
Total Surface Area Of cuboid = 2(lb+bh+hl)
= 2(20X10+10X10+10X20)
= 2(200+100+200)
= 2(500)
= 1000 cm²
