Solution

The correct option is B $214 m^{2}$

Surface area of the cuboid having length, breadth and height as $l, b$ and $h$ respectively is given as $2 (l b + b h + h l)$

Brick has the shape of cuboid. Let $S$ be the require surface area.

$S = 2 (5 \times 6 + 6 \times 7 + 7 \times 5)$

$2 (30 + 42 + 35)$

$214 m^{2}$
