a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. what is the surface area of the pri
laiz [17]

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

SA = A_ {l} + 2B

Where:

A_{l}: Is the lateral area

B: It is the area of the base

A_ {l} = P.h

Where:

Q: It is the perimeter of the base

h: It's the height

A_ {l} = 40 * 4\\A_ {l} = 160 \ in ^ 2

On the other hand:

B = 12 * 8\\B = 96 \ in ^ 2

So, we have:

SA = A_ {l} + 2B\\SA = 160 \ in ^ 2 + 2 * 96 \ in ^ 2\\SA = 352 \ in ^ 2

Answer:

SA = 352 \ in ^ 2
