1.	20t tro cubes of 10 cm edge are joined end to end, then the surface area of the resulting cuboid isai 1200() 1000(c) 800(d) 1400
Answer» When edge of 10 cm Cube join together the dimensions of formed cuboid areLength (l) = 20 cmBreadth(b)=10 cmHeight (h)=10 cm______________________________________________________________Total Surface Area Of cuboid = 2(lb+bh+hl) = 2(20X10+10X10+10X20) = 2(200+100+200) = 2(500) = 1000 cm²
