Answer:
592
Step-by-step explanation:
Surface area of a rectangular prism = 2lw + 2lh + 2wh
where w = width, h = height and l = length
These are the given dimensions...
length = 12 cm
width = 8 cm
height = 10 cm
To find the surface area we plug in the given values into the formula
[tex]SA=2(12)(8)+2(12)(10)+2(10)(8)\\12*8=96\\96*2=192\\12*10=120\\120*2=240\\10*8=80\\80*2=160\\160+240+192=592[/tex]
Hence, the surface area of the rectangular prism is 592
