The height of cuboid is 3 cm

Step-by-step explanation:

Total surface area of cuboid = 2lb+2bh+2hl

Length of cuboid = 10 cm

Width of cuboid = 2 cm

Let the height be x

Total surface area of cuboid = 2(10)(2)+2(2)(x)+2(x)(10)

Total surface area of this cuboid is 112 cm squared

2(10)(2)+2(2)(x)+2(x)(10)=112

40+4x+20x=112

40+24x=112

24x=112-40

24x=72

$x=\frac{72}{24}$

x=3

Hence the height of cuboid is 3 cm
