The surface area of the rectangular prism is 2(lw + wh + lh). A rectangular prism has six rectangular faces.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle with length and width is
Area = length × width
I.e., A = l × w sq. units
<h3>How to calculate the area of the rectangular prism?</h3>
A rectangular prism has six rectangular faces and the length 'l', width 'w', and height 'h'.
So, the areas of each face are as follows:
A(R1) = l × w
A(R2) = l × h
A(R3) = w × h
A(R4) = l × w
A(R5) = l × h
A(R6) = w × h
Thus, the area of the prism = sum of areas of all the faces
⇒ Area of the prism = lw + lh + wh + lw + lh + wh
⇒ A = 2lw + 2lh + 2wh
⇒ A = 2(lw + lh + wh)
Therefore, the area of the rectangular prism is A = 2(lw + lh + wh).
