The problem is asking you to solve for the surface area of the triangular prism. You know that the prism is made up of two triangles and three square surfaces. Adding these surface together, will give you the surface area.

Solving for the surface area:

Surface area of 2 triangles (top and bottom) + Surface area of 3 rectangles (sides)

2 [1/2 (2.6)(3.9)] + [ (4.3)(3.9) + (4.3)(2.6) + (4.3)(5.2) ] = 60.45 cm^2 surface area

Using the given equation:

10PI/X = 240/360

Cross multiply:

(10PI*360) = (240*X)

3600PI = 240X

Divide both sides by 240:

X = 3600PI / 240

X = 15PI in^2
