Answer:

Step-by-step explanation:

l = 5 in

w = 5 in

h = 12 in

Surface area of rectangular prism = 2*(lw +wh + hl)

 = 2*(5*5 + 5*12 + 12*5)

  = 2*(25 +60 +60)

  = 2*145

  = 290 in²

Answer:
290
An easy way to do it is 60 *4 because there are 4 rectangles = 240 and 25 *2 for the two squares =50
240+50=290
But u can also do it another way
