The surface area of any object is the sum of the areas of all the faces. In this case, we have a rectangular prism with dimensions 8x4x3 and a trianglar prism with a 8x4 rectangular base and height of 6.
Let's start with the rectangular prism. We have the bottom which is 8x4, two sides that are 3x4, and two sides that are 8x3.
8*4 + 2*3*4 + 2*8*3 = 104 in^2
Now that's find the surface area of the trianglar prism. We have the rectangular side on top which is 10x4, the rectangular side on the right which is 6x4, and two triangles that are 8 long and 6 high.
10*4 + 6*4 + 2*0.5*8*6 = 112 in^2
The total surface area is 104 + 112 = 216 in^2
Answer:
2x^2 + 8x + 3
Step-by-step explanation:
The expression is not factorable with rational numbers.
Answer: Seems like it would depend on your base. Can you pull the ladder away from the window and let it go and it drops back to the original position? I would prefer an extension ladder with a set off just below the frame so that I can reach both panes without the ladder blocking me. If the extension ladder won’t reach I would use the WFP (and might use that anyway).
The height of the barrel is 6 feet.
For this question, we want to find out the greatest amount of area of pizza for the least amount of money:
So we have two pizzas with a 10 in. diameter. Let us take one of those pizzas.
The formula for area of a circle is

; So the area for one of these 10 in. pizzas would be

or 25

.
We have two of these pizzas, so the total area that we would get with $14 would be 25

*2 or 50

.
For the second case, we have one pizza with a 14 in. diameter.
The area of this pizza will be

or 49

.
So for $15 we can buy 49

worth of pizza.
The best deal would be to buy the two medium pizzas of 10 inch diameter, because for $14, you get 50

.
