Answer 1

Surface area of a rectangular prism:

`SA=2(wl+hl+hw)`

Substitute 1.2 for all of the variables in the formula:

`SA=2[(1.2)(1.2)+(1.2)(1.2)+(1.2)(1.2)]`

Using a calculator, you should get an answer of:

`SA=8.64\text{ }yd`

The answer is that the surface area of this shape is 8.64 yards.
