Respuesta :

calculista
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
