Answer:

The height of cuboid is 3 cm

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=(72)/(24)


x=3

Hence the height of cuboid is 3 cm
