Question

Surface area!!!!!!!!!!!!!!

Answer 1

Answer:

D.347.45cm²

Step-by-step explanation:

The formula to find the surface area of a rectangular prism is:

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

Let's break down our variables:

Length = 11.73cm

Width = 9.08cm

Height = 3.23cm

Let's substitute the values:

$A=2)(9.08)(11.73)+(3.23)(11.73)+(3.23)(9.08))$

$A=2(106.508+37.888+29.328)$

$A=2(173.7247)$

$A=347.45$cm²
