OpenStudy (michele_laino):

we have the base whose area is: 4*4=...?

OpenStudy (rebeccapink6398):

16

OpenStudy (michele_laino):

ok!

OpenStudy (michele_laino):

then we have four triangles. The area of each triangle is: (4*6)/2=...

OpenStudy (rebeccapink6398):

12+16?=28

OpenStudy (michele_laino):

no, since we have four triangle, so the requested area is: (4*12)+ 16=...?

OpenStudy (michele_laino):

triangles*

OpenStudy (rebeccapink6398):

what? 4*12? why

OpenStudy (michele_laino):

since the area of each triangle, is 12, and we have four of such triangles, so the total lateral area is: 4*12

OpenStudy (rebeccapink6398):

so then 48+16?

OpenStudy (michele_laino):

that's right!

OpenStudy (rebeccapink6398):

yay thanks, can you help me with another question?

OpenStudy (michele_laino):

ok!

OpenStudy (rebeccapink6398):

yay! so i think do we do as before in the last question?

OpenStudy (michele_laino):

as for previous exercise, we have the base whose side is 32 inches, so the corresponding area is: 32*32=...?

OpenStudy (michele_laino):

yes! we have to do as in the last question

OpenStudy (rebeccapink6398):

ok :D and i got 1024 and thennn we umm times the base and triangles?

OpenStudy (rebeccapink6398):

okay i think i did it right? I got D

OpenStudy (michele_laino):

yes! we have four triangles, and the area of each of them is: (32*36)/2=...?

OpenStudy (michele_laino):

is the question clear?

OpenStudy (rebeccapink6398):

yes and yay! okay one last question if you dont mind? :)

OpenStudy (rebeccapink6398):

i was taought to open it up and then find it. i color coated them XD

OpenStudy (michele_laino):

ok!

OpenStudy (michele_laino):

what is the height of the prism? I don't see it!

OpenStudy (rebeccapink6398):

i think it may be 7

OpenStudy (michele_laino):

ok!

OpenStudy (michele_laino):

we have two rectangles, and the area of each of them is: 9*4=...?

OpenStudy (rebeccapink6398):

36.....36*2=72

OpenStudy (michele_laino):

that's right!

OpenStudy (michele_laino):

then we have two rectangles, and the area of each of them is: 4*7=...?

OpenStudy (rebeccapink6398):

28...28*2=56

OpenStudy (michele_laino):

ok! Finally we have two rectangles, and the area of each of them is: 7*9=...?

OpenStudy (rebeccapink6398):

63....63*2=126

OpenStudy (michele_laino):

that's right! So, the requested area is given by the subsequent computation: 72+56+126=...?

OpenStudy (rebeccapink6398):

254 :D yayayaya thank you

OpenStudy (michele_laino):

thank you! :)

OpenStudy (rebeccapink6398):

OpenStudy (rebeccapink6398):

have a great rest of your day :)

OpenStudy (michele_laino):

congratulations!!!!! :)

OpenStudy (michele_laino):

thanks! :)
