Can someone please help me with this Geometry problem?

Question

I've asked this question on another website and they said to "do the simple calculations", but they aren't explaining it very well. Can someone please help me with this?

Question:

What is the lateral area, in square inches, of the regular triangular prism? The length (points C and C) is 16 inches. The side length (points B and C) is 6 inches.

Answer 1

Regular triangular means that the triangle is equilateral.

Begin by labeling all edges accurately.

Area of equilateral triangle is e√3 / 4. There are two triangles.

The area of each lateral face is (6)(16) and there are three.

Do these calculations and add.
