The ratio of the length to the width to the height of a rectangular box is 12:4:7. The sum of the length and the width is 32 inches. Find the surface area of the box.

The surface area of the box is .

Step-by-step explanation:

Given that,

Ratio of the length to the width to the height of a rectangular box is

The sum of the length and width of box is

From the question,

Dimension of Rectangular box are .

  Let the side of rectangular box is x.

Now,   Sum of length and width is

 Then,                

      ⇒                        

      ⇒                            

Here we get the dimensions are,

Then,  surface Area of rectangular box =

                                                                 =

                                                                 =

                                                                 =

Hence,

The surface area of the box is .

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

me i beg !
