Question

Two cubes of edge $6cm$ are joined to form a cuboid. Find the total surface area of the cuboid.

Answer 1

Length of the resulting cuboid $=12cm$ $\left(l\right)$

Breadth of the resulting cuboid $=6cm$ $\left(b\right)$

And the height of the resulting cuboid $=6cm$ $\left(h\right)$

The total surface area of the cuboid is $=2(lb+bh+lh)$

$=380{cm}^2$
