Question

What is the surface area of this rectangular prism?

Answer 1

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

Answer 2

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
