A rectangular prism's surface area is
.
2·(10·5+2·5+2·10)=160.
Well, first you would estimate all the terms: 10.2 to 10, 2 to 2(keep the same), 3.7 to 4, and eight to eight.
So you have 10 x [(2 x 4) + 8]
then you would evaluate this expression using order of operations
10 x [(2 x 4) + 8]
10 x [8 + 8]
10 x 16
160
