The surface area is made up of six sides and the area is then just the sum of the areas of the six sides...
A=2xy+2xz+2yz
A=2(xy+xz+yz) in this case:
A=2(5*4.5+5*3.5+4.5*3.5)
A=2(22.5+17.5+15.75)
A=2(55.75)
A=111.5 in^2
Could you take another photo with you zoomed a lil bit more so I can answer it?

Answer:
Given:
- Sale prices at the Ajax Outlet Store are 50% below the original prices.
- On Saturdays, an additional discount of 20% off the sale price is given.
To find:
- The Saturday price of a coat whose original price is $180.
The formula used to calculate the percentage is (value/total value)*100%.
Step-by-step explanation:
Step 1 of 2
The original price of coat = $180
Ajax always sells at 50% discount
So their sale price = $90
Step 2 of 2
On Saturdays they sell 20% less
Which implies-
1/5*90 = 18
90-18=72
They sell at $72 on Saturday.
