Find the surface are of the prism.

The surface area of the prism is 161 square feet.

Step-by-step explanation:

Step 1:

In order to calculate the surface area of the entire prism, we must calculate the individual areas of all the sides.

The triangular prism consists of 2 triangles and 3 rectangles.

Step 2:

The area of a triangle is half the product of the base length and its height.

The triangles have a base length of 5 feet and a height of 5 feet.

The area of 2 triangles =

Step 3:

The area of a rectangle is the product of its length and width.

There a 3 rectangles out of which 2 are similar.

The similar rectangles have lengths of 8 feet and widths of 5 feet.

The area of 2 similar rectangles

The third rectangle has a length of 8 feet and a width of 7 feet.

The area of the third rectangle

Step 4:

The surface area of the prism = The area of the 2 triangles + The area of the 3 rectangles.

The surface area of the prism

The surface area of the prism is 161 square feet.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
