Answer 1

@e.mccormick ?

Answer 2

can you identify or spot the individual faces of this 3D figure?

Answer 3

Uhmmm what do you mean?

Answer 4

Here is the surface area of a right triangular prism:

Answer 5

can you picture this as a real object that you can pick up and rotate around?

Answer 6

I guess?

Answer 7

how many faces does this 3D figure have?

Answer 8

5

Answer 9

correct, are you able to find the area of each face?

Answer 10

No that's where I need help at @jim_thompson5910

Answer 11

ok let's just focus on the triangles for now

Answer 12

The two triangles are the same (ie congruent) so we only need to find the area of 1 triangle and double it

Answer 13

what is the area of one of the triangles?

Answer 14

I'm honestly completely lost as to what to do to even find the area.

Answer 15

Area of triangle = (base*height)/2

Answer 16

I can't tell which is base and which is height in the triangles either though-

Answer 17

it really doesn't matter as long as the base and height are perpendicular

Answer 18

the base is ALWAYS perpendicular to the height (they meet at a right angle)

Answer 19

??

Answer 20

do you see how I came up with that?

Answer 21

not really-but ok

Answer 22

oh wait now i do

Answer 23

again you kinda have to imagine picking this object and rotating it around (as if it were a real object in 3D space)

Answer 24

yeah but how do i get the answer because I need to get this done asap ;-;

Answer 25

what's the area of the triangle I drew last?

Answer 26

24?

Answer 27

correct

Answer 28

1 triangle area = 24
2 triangles area = 48

Answer 29

so what do I do now?

Answer 30

now we move onto the rectangles

Answer 31

the top most face, what is the area of that face?
