Question

three cubes of side 6 cm are joined end to end. find the Surface area of the resulting cuboid.​

Answer 1

Answer:

Length of each side of cubes = 6cm

Now, 3 cubes are joined end to end

So, the Length of resulting cuboid will be 6+6+6 = 18cm

But the Breadth and Height will remain same

So, Breadth = 6cm and Height = 6cm

Surface area of resulting cuboid

\begin{gathered}\bf= 2(lb + bh + hl) \\\\= 2(18 \times 6 + 6 \times 6 + 6 \times 18) \\\\= 2(108 + 36 + 108)\\\\= 2(252) \\\\= 2 \times 252\\\\= 504\end{gathered}

=2(lb+bh+hl)

=2(18×6+6×6+6×18)

=2(108+36+108)

=2(252)

=2×252

=504
