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.
