9. A rectangular prism has a height of 3 inches, a width of 1 foot and a length of 18 inches. What is the volume of the prism in cubic feet? What is the volume of the
prism in cubic inches? Which measure ft or in' is better?

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
