Explanation:

At first you need to take its lateral surface area by using the perimeter of base of the triangle and the height of prism.

Then after calculating it you need to find out its total surface area which is asked in the question and that is calculated by adding the area of both triangles of the prism in the lateral surface area.

Then that's your answer.

Answer:

544 square units

Explanation:

The surface area is the sum of the area of the two triangular bases and the three rectangular faces. The relevant area formulas are ...

A = 1/2bh . . . . area of a triangle with base b and height h

A = LW . . . . . are of a rectangle of length L and width W

__

SA = 2(1/2)(12)(8) + (10 +10 +12)(14)

SA = 96 +448 = 544 . . . square units
