Answer:
D.347.45cm²
Step-by-step explanation:
The formula to find the surface area of a rectangular prism is:
[tex]A=2(wl+hl+hw)[/tex]
Let's break down our variables:
Length = 11.73cm
Width = 9.08cm
Height = 3.23cm
Let's substitute the values:
[tex]A=2)(9.08)(11.73)+(3.23)(11.73)+(3.23)(9.08))[/tex]
[tex]A=2(106.508+37.888+29.328)[/tex]
[tex]A=2(173.7247)[/tex]
[tex]A=347.45[/tex]cm²
