Asolid is composed of squares and equilateral triangles. its net is shown below:

the area of each triangle is 1.5 square units. the surface area of the triangular prism is square units. (input whole number only.)

There are 3 squares, each with surface area A=(2 inches)(2 inches) = ? square inches.  Multiply this result by 4.  Total area?

There are 2 triangles, each with surface area A =1.5 inches.  Total area = ?

Now add together the 2 total areas.

4+2=-2. 1+2=3. y=-2/3x+b. 2=4/3+b. 2/3=b. the answer is y= -2/3x+2/3
