Question

I need help. Will fan and metal for the first one to give me the CORRECT answer.

Answer 1

A. 2520 cm^2
B. 2792 cm^2
C. 4080 cm^2
D. 2280 cm^2

Answer 2

Answer 3

Anyone?

Answer 4

You have to calculate the surface area of 5 planes.

Answer 5

what?

Answer 6

I never learned that!

Answer 7

The 2 triangles on the end. They are each 24 by 10 so together their surface area is 240.

Answer 8

And that is just for the two triangles, right?

Answer 9

wouldnt I have to do something with the rectangles?

Answer 10

The rectangle at the back is 34 by 10 so its suraface area is ?

Answer 11

340 but there is two of them. So would I have to add 340 + 340 to get the surface area of those?

Answer 12

the rectangles?

Answer 13

No. The only planes that are equal are the 2 triangles which we already calculated.
The bottom rectangle is 24 by 34 with an area of 816

Answer 14

so now we have to do something with the calculations with the triangles and with the calculations of the rectangle.

Answer 15

The top rectangle (the slanted rectangle) is 34 by 26 = 884
NOW we have all the areas calculated.

Answer 16

so now do we add them all together?

Answer 17

to get the surface area?

Answer 18

Yes, add the triangle area to the 3 rectangle area

Answer 19

and then thats the answer?

Answer 20

Yes, it should be.
So add 240 + 340 + 816 + 884

Answer 21

You do have the answer don't you?

Answer 22

2280 is the answer?

Answer 23

Sorry, I was trying to make my lunch.

Answer 24

That is the answer - and that's 'd' right?
