PLEASE HELP ME ITS URGENT

1. A = area of frame; s = length; w = width

2. A = 15^2 - (15 - 2(2))^2 = 225 - 121 = 104

3. A = 18^2 - (18-2(3))^2 = 324 - 144 = 180 --> 180 square inches *20 cents = 3600 cents = $36

In order to find this, you have to find both the top and the bottom volumes and add them together. To find the bottom volume you’d use the formula lwh or Length*width*height. First you’d substitute in the numbers for the formula and get 9yd*8yd*4yd and get 288yd cubed. Then to find the top one you use the same formula and use 4yd*3yd*2yd and get 24yd cubed. Finally you add the two volumes together and get 288yd cubed + 24yd cubed=312yd cubed
