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

I need help understanding this. SO please help and give explanation

NikAS [45]

So my understanding from this you have to make it y = mx + b so m stands for the slope there’s different ways to find it as shown in the first picture. I’ll try to make another comment since this only lets me take one picture at a time.
