Find the volume V of the described solid S. A frustum of a pyramid with square base of side b, square top of side a, and height h V = What happens if a = b? (Enter your answer in terms of b and h.) We get a with volume V = . What happens if a = 0? (Enter your answer in terms of b and h.) We get a with volume V = .

V = (a-b)²y²/h + 2b(a-b)y+b²/h

Step-by-step explanation:

Find attached the solution with the diagram of a frustrum pyramid.

nope

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
