To keep heating costs down for a structure, architects want the ratio of surface area to volume as small as possible. an expression for the ratio of the surface area to volume for the square prism shown is 2b+4h/bh. find the ratio when b=12 ft and h=18ft.

The ratio when b = 12 ft and h = 18 ft is 5/6. You get this answer in the following steps :

10/12 can be simplified down

Divide both sides by 2, then see what needs to be simplified more

10/2 = 5

12/2 = 6

Since you have an odd and even number, you can't simplify it any more, as 5 and 6 have no common numbers.

Your answer is: 5/6 

Have an amazing day mate!

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
