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 :)))
4.50x+3x=1140
You will add 4.50 and 3 together to get 7.5.
your equation is now...
7.50x=1140
you divide by 7.5 and get 152. so x= 152.
I am stuck now.
