Example Problems For Surface Area Of Rectangular Prism Calculator

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

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
