A rectangular concrete driveway is 30 feet long, 8 feet wide, and 6 inches thick. What is the volume of the concrete?

v=120f³

Step-by-step explanation:

To find the volume first all of the units must be the same.

i.e. feet, feet and feet.

1 feet=12 inch

 ?     =6 inch

V=lwh

 =30f×8f×0.5f

 =120f³

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
