Question

Two cubes each of side12cm are joined end to end. What is the surface area

Answer 1

Answer:

Step-by-step explanation:

Two cubes of each side = 12cm

Joined end to end

length = 12+12 = 24cm

height = 12cm

breadth = 12cm

Total surface area of new cuboid formed

=2(lb+bh+hl)

=2(24*12+12*12+12*24)

=2(288+144+288)

=2(720)

=2*720

=1440

Hence, total surface area of new cuboid formed = 1440cm sq.
