Arectangular prism is 6 inches long, 3 inches wide, and 2 inches high. what is its surface area?

Area of a rectangular prism=2(long * wide) + 2(long* high)+2(wide* high)
Data:
long=6 in
wide=3 in
high=2 in-

Area of this rectangular prism=2(6 in* 3in)+2(6 in * 2 in)+2(3 in * 2 in)=
=2(18 in²)+2(12 in²)+2(6 in²)=36 in²+24 in²+12 in²=72 in²

the surface area of this rectangular prism is 72 in².
