The correct answer for the question that is being presented above is this one: "C) 1.6." Hank is painting his grandfather's fence. He painted 40 linear feet in 85 minutes. He still has 360 linear feet to paint. His cousins, Sam and Alex, come to help. Sam paints twice as fast and Alex paints half as fast as Hank. The constant of proportionality that relates the current fence painting rate is 1.6.

Find the length of the prism if the width is 12 feet, the height is 18 feet, and the volume of the prism is 3240 cubic feet.

olga55 [171]

Known :

w = 12 feet

h = 18 feet

V = 3.240 feet³

Asked :

l = ...?

Answer :

V = l × w × h

3240 = l × 12 × 18

3240 = 216 l

l = 3240 ÷ 216

l = 15 feet

So, the length is 15 feet

Hope it helps and is useful :)
