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 . find the ratio when b = 10 ft and h = 12 ft.

Ratio=

Step-by-step explanation:

Surface Area of Square Prism =

Volume of square prism =

Ratio =

Put the values of  b = 10 , h = 12

Ratio =

Ratio = [text]\frac{200+480}{1200}[/text]

Ratio=

Ratio =

step-by-step explanation:

- 4, v72, 32/5

i think this is right.

hope it
