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 = 15 ft and h = 10 ft.

The ratio is when b = 15 ft and h = 10 ft.

Step-by-step explanation:

The ratio of the surface area to volume for the square prism is given by the expression

We have to find the ratio when b = 15 ft and h = 10 ft.

Substitute b=15 and h=10 in the given expression.

Therefore the ratio is when b = 15 ft and h = 10 ft.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
