Rectangular prism is a 3-D geometric shape which has length, width and height. The surface area of the rectangular prism is the sum of the area of each side of the prism. Rectangular prism surface area calculator is the instant online tool which can calculate the surface area of the rectangular prism given its dimensions.


Example 1: Calculate the surface area of the rectangular prism which has length of 5m, width of 3m and height of 2m.

Given ->  Length, l = 5m

Width, w = 3m

Height, h = 2m

Surface area of the rectangular prism, SA = 2lw + 2lh + 2wh

SA = (2* 5* 3) + (2* 5* 2) + (2* 3* 2)

SA = 30 + 20 + 12 = 62m2

Surface area of the rectangular prism, SA = 62m2


 
Example 2: Calculate the surface area of the rectangular prism which has length of 6cm, width of 4cm and height of 8cm.

Given ->  Length, l = 6cm

Width, w = 4cm

Height, h = 8cm

Surface area of the rectangular prism, SA = 2lw + 2lh + 2wh

SA = (2* 6* 4) + (2* 6* 8) + (2* 4* 8)

SA = 48 + 96 + 64 = 208cm2

Surface area of the rectangular prism, SA = 208cm2
