Find the surface area of the given cuboid.

Concept: The surface area of a cuboid can be defined as the total amount of the area of all its surfaces. Because a cuboid is a three-dimensional solid shape, its surface area is determined by its length, width, and height.

Here, $l=5,b=3,h=4$

Surface area of cuboid $=2(lb+bh+lh)$

$\Rightarrow 2(5\times 3+3\times 4+5\times 4)$

$\Rightarrow 94{\text{cm}}^2$

Hence, the surface area of given cuboid is $94{\text{cm}}^2$.
