Question

if two cubes of side 10cm are joined to each other face to face ,find the total surface area of the new cuboid?​

Answer 1

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
