The surface area of the rectangular prism is 312in^2
Data Given;
- length = 12in
- width = 8in
- height = 3in
Surface Area of a Rectangular Prism
The surface area of a rectangular prism is the sum total areas of the given sides.
The formula is given as
[tex]A = 2[(length * height) + (length * width) + (width * height)\\
A = 2[(lh) + (lw) + wh)]\\
[/tex]
let's substitute the values into the formula above
[tex]A = 2[(12*3) + (12*8) + (8*3)]\\
A = 2(36+96+24)\\
A = 2*156\\
A = 312in^2[/tex]
