  1. Find the surface area of rectangular prism having length, width and height 7cm, 6cm and 5cm respectively.


    Step 1 :  

    Given,


    Length(l) = 7cm


    Width(w) = 6cm


    height(h) = 5cm



    Step 2 :  

    Surface Area of rectangular prism = 2(lw + lh + wh)


    = 2(7×6 + 6×5 + 7×5)


    = 2( 42 + 30 + 35)



    Step 3 :  

    Surface Area of Rectangular Prism = 214 cm2



    Answer  :  

    214 cm2



  2. Find the surface area of a rectangular prism having length, width and height 8cm, 4cm and 5cm respectively


    Step 1 :  

    Given,


    Length(l) = 8cm


    Width(w) = 4cm


    Height(h) = 5cm



    Step 2 :  

    Surface Area of rectangular prism = 2(lw + lh + wh)


    = 2(8×4 + 4×5 + 8×5)


    = 2(32 + 20 + 40)



    Step 3 :  

    Surface Area of rectangular prism  = 184 cm2



    Answer  :  

    184 cm2
