Question

Find the surface area.

  1. 556 cm2    
  2. 278 cm2    
  3. 680 cm2    
  4. 340 cm2    

hintHint:

The Formula of the surface area of cuboid is 2 left parenthesis l b plus b h plus l h right parenthesis, where l is the length of the cuboid b is the breadth of the cuboid and h is the height of the cuboid.

The correct answer is: 556 cm2


    The Formula of the surface area of cuboid is 2 left parenthesis l b plus b h plus l h right parenthesis, where l is the length of the cuboid b is the breadth of the cuboid and h is the height of the cuboid.
    Step1: Calculating the Surface area of cuboid
    Here we are given the length of the cuboid as 10 and breadth of the cuboid as 17 and height of the cuboid as 4. By putting the value of l, b, h in the formula, we will get the total surface area.
    2 left parenthesis l b plus b h plus l h right parenthesis
    =>2 left parenthesis 10 cross times 17 plus 17 cross times 4 plus 10 cross times 4 right parenthesis
    =>556 space c m squared
    So, the surface area of the cuboid is 556 space c m squared.
