Question

Two cubes have edge 10m each.Their edges have been joined to form cuboid.What will be the surface area of cuboid thus Formed?

Answer 1

Heya mate, Here is ur answer

New Dimensions become :

length=10+10

=20 m

Breadth=10 m

Height=10 m

SA of New cuboid=2(lb+bh+hl)

=2(20×10+10×10+10×20)

=2(200+100+200)

=2×500

$= 1000 \: m {}^{2}$

So, SA of New cuboid=1000 m^2
