For the second part I will give you a hint: Look at the hyptoptuse on the right triangles how long is the rectangle on there???

To calculate the surface area is basicall calculating area all that is neccessary is for you too look where the values line up find the area's and add them I will help you get in to the right direction though I will Identify for you what you need to multiply You should be becoming familar with how to do this.

Right triangle \(5 * 12 = area\) 

Right triangle \(5 * 12 = area\)

Rectangle that slants along the hypnotuse \(13 * 15 = area\) 

Rectangle under the prism \(12 * 15 = area\) 

Rectangle in the back of the prism \(5 * 15 = area\) 

All you have to do is add products of these problems and tell me what you get.....

To calculate the area of this figure we need to know the area of the parrallogram and rectangle the shapes are clearly outlined so we don't need to worry on which thing to find...... 

The formula to find the area of a parallogram is.

\(Area = Base*Height\)

The Formula of a rectangle is. 

\(Area = length * With\) 

Then we work out are problem and calculate the following   

Using the formula for the rectangle we look at the length of the each sides we never want to calcualte to SIDES or LINES THAT ARE PARALLEL in a rectangle

and by looking at the rectangle we can see it has a  

With of 7.3 inches  

& 

Length of 48.2   

Now we multiply them together and are product will be the area of the rectangle. 

\(7.3 * 48.2 = 351.86\) 

So this mean are current value and the are of the rectangle is 351.86 Sq inches  

Now all we have to do is find the area of the parallogram which I find similar to finding the area of a rectangle 

We see that the parrallogram has an exact base as the rectangle and has a height of 13.4 Sq inches so we multiply them together 

\(48.2 * 13.4 = 645.88\)

So now we know the parralogram's area is equal to 645.88 sq inches so now all we have to do is add are area's and find our answer. 

\(351.86 + 645.88 = 997.74\)

so we now know are toal area is 997.74 Sq inches.

Of course the answer is was clearly given by you I just might have a go 

\(7456 \times 9852 = 7345612.0\)

Who know maaybe you might need a brsuh up on your multiplication skills.

LOL yeah XD

I'm not sure if you interpeted what I said correctly.

We can how many square feet/Area of this quaderatiearal by breaking it down into smaller shapes we can can solve for the area by breaking it into two shapes actuallywhen the main rectangle pushes up we can cut that one off and find the area for it first  

Little Rectangle 

\(4 * 3 = 12\)

Are current area is twelve now 

Now we can move on to the bigger rectangle 

bigger rectangle 

\(6 * 14 = 84\)

and

\(12 + 84 = 96\) 

So are total area is 96 Square Feet

OOOOOH Wow that really makes sense XD can't beilive I did that I could have just multiplied the triangles all together.......

Oh I se Thank you I was just curious because he has numbers at the botom and two of them are the same as the height of the other triangles so I though the other two were the ones that weren't labeled so that kind of was my reasoning for my answer....  

The net of a square pyramid is shown:



What is the surface area of the figure?

0.65 square inch 0.50 square inch 0.40 square inch 0.25 square inch 

I Didn't know how to include the pic so I have it like that : )
