Find the surface area of the triangular prism formed by the net (the volume is 3.46)

Answer 1

So you know your volume is \(\frac{1}{2}*b*h*l\), are the other dimensions you have in your drawing given to you?

Answer 2

If so, all you need do is solve for your 'l' in this equation, this in turn will give you all the dimensions necessary to solve for your surface area.

Answer 3

All the edges are 2 and then the triangle is give
im still don't understand @eSpeX

Answer 4

You have all the information you need to solve this. They have given you all of the edges, so you just need to plug the information in. What is your 'b', 'h', and 'l'?

Answer 5

the bace and hight are 2 and would the lengs be 3sqrt

Answer 6

Good, so now you can use those to find the area of the two triangles, add them to the area of the three rectangles, and you have your total surface area.
The area of each triangle is what?
The area of each rectangle is what?

Answer 7

area of the 2 triangle is 13.86
are of the 3 rectangle is 12
then do I add them together??

Answer 8

How did you get 13.86 for the area of the two triangles?

Answer 9

i took 2X2X3sqrt =6.93X2=13.86

Answer 10

The area of a triangle is \(\frac{1}{2}*b*h\) and you have two of them.

Answer 11

so the area of one triangle would be 2
2x2=4 is the area of both triangles

Answer 12

As you have an equilateral triangle, your area is going to be \(\frac{1}{2} * 2 * \sqrt{3}\) for each of your triangles.

Answer 13

Ok thanks for the help i think i got it from here
much apprecated

Answer 14

You're welcome.
