HELP! 20 points!
Olin [163]

The answer is : $36.36

Step-by-step explanation:

The given box is a rectangular box. To find the felt needed to cover the box, we need to find the surface area of the rectangular prism.

Surface area of a rectangular prism = 2(l*w + w*h + h*l), where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.

Given: l = 11 inches; w = 8 inches; and h = 6 inches.

Now plug in these given values in the above formula, we get

Surface area of the rectangular prism = 2 (11* 8 + 8*6 + 6*11)

= 2(88 + 48 + 66)

= 2(202)

= 404

The surface area of the rectangular prism = 404  square inches.

The felt cost 9 cents square inches.

Convert 9 cents to dollar.

9 cents = $0.09

To find the cost of the felt needed to cover prism multiply 404 by 0.09

The total cost = 404*0.09 = $36.36

Hope this helped :)))
