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

Write the equation of the ellipse using the given information:

horsena [70]

We know, equation of ellipse is given by :

$\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1$

Here,

(h,k) is centre of the ellipse = (0,0).

a = major axis = 8.

b = minor axis = 4.

Putting all given value in above equation, we get :

$\dfrac{(x-0)^2}{8^2}+\dfrac{(y-0)^2}{4^2}=1\\\\\dfrac{x^2}{8^2}+\dfrac{y^2}{4^2}=1\\\\\dfrac{x^2}{64}+\dfrac{y^2}{16}=1$

Hence, this is the required solution.
