9mm on the left side 3mm tall and 13mm wide

Answer 1

Surface area of rectangular prism= 2(wl+hl+hw)

So,

➠ 2(13×9 + 3×9 + 3×13)

➠2 × 183

Ans ➠ 366mm²

Answer 2

`Area = 3.66 * 10^(-2)`

Explanation:

Formula to find area of rectangular prism:

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

Add the values in the formula & solve:

`A=3.66 * 10^(-2)`

I hope this helps :)
