Arectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. what is the surface area of the prism?

For this case we have that the surface area of the prism is given by:

Where:

: Is the lateral area

B: It is the area of the base

Where:

Q: It is the perimeter of the base

h: It's the height

On the other hand:

So, we have:

The surface area of prism = 352 square inches

Step-by-step explanation:

Formula:-

Surface are of rectangular prism = 2(lb + bh + lh)

l - Length of prism

b - width of prism

h - Height of prism

It is given that,a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height.

To find the surface area of prism

l = 12 inches

b = 8 inches

h = 4 inches

surface area =  2(lb + bh + lh) = 2(12*8 + 8*4 +12*4)

  = 2(96 + 32 + 48) = 352 square inches.

Therefore the surface area of prism = 352 square inches
