Answer:

LA = 120 sq cm

SA = 132 sq. cm.

Step-by-step explanation:

LA = ph where p = perimeter of the base and h = the height of prism.

Your base is a triangle. The third side = $\sqrt{5^{2} - 3^{2} }$ = $\sqrt{25 - 9} = \sqrt{16} = 4$

Now, the perimeter of the triangle is 3 + 4 + 5 = 12

So, LA = 12(10) = 120 sq cm

The area of the base is the area of a triangle. A = bh/2 = 4(3)/2 = 6

SA = 2B + LA where B is the area of the base

SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.
