$\huge \green{Answer}$

$\: \tt → 94cm {}^{2}$

$\bf \: Given : \\ \tt Length(l) = 5cm \\ \tt \: breadth(b) = 4cm \\ \tt \: height(h) = 3cm \\ \\ \bf \: Apply \: formula : \\ \bf \tt \: Surface \: \: area \: \: of \: \: a \: \: cuboid \: \\ \tt \: = >2(lb + bh + hl) \\ \\ \tt = > 2(5 \times 4 + 4 \times 3 + 3 \times 5) \\ \tt \: = > 2(47)cm \\ \\ \tt = > {94cm}^{2}$

Answer 2

Answer: 94cm squared

Step-by-step explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

2(12) + 2(15) + 2(20)=

24 + 30 + 40 =

54 + 40=

94
