Atriangular prism with bases that are right triangles measuring 5 inches by 12 inches by 13 inches. the height of the the prism is two inches. find the surface and and show work,

We know that
[surface area]=2*[area of the base]+perimeter of the base*height

area of the base
the base is a right triangle
b=5 in
h=12 in
area of the base=5*12/2> 30 in²

perimeter of the base=5+12+13> 30 in

height of the prism=2 in

[surface area]=2*[30]+30*2> 60+60> 120 in²

the answer is
120 in²
