Find the lateral surface area and the total surface area.
serious [3.7K]

Answer:

LA = 96

SA = 108

Step-by-step explanation:

The lateral surface area is the area of the sides (not including the bases).  For a triangular prism, the bases are the triangles.

The sides consist of three rectangles.  The vertical rectangle is 3 by 8 units.  The horizontal rectangle is 4 by 8 units.

The slanted rectangle has a length of 8 units, but we don't know the width.  To find that, we use Pythagorean theorem to find the hypotenuse of the triangles.

c² = a² + b²

c² = 3² + 4²

c = 5

So the lateral surface area is:

LA = (3)(8) + (4)(8) + (5)(8)

LA = 96

The total surface area is the lateral surface area plus the area of the bases.

SA = 96 + ½(3)(4) + ½(3)(4)

SA = 108
