Suppose you want to buy a concrete for a 36 ft by 24 ft by 9 in. patio. If concrete costs $55/yd cubed, how much will the concrete for the patio cost?

So, we need to find the volume.

Convert to similar units

12 yards by 8 yards by .25 yards

Multiply together, assuming it is a block patio

13*8*.25 = 26

So 26 yards cubed.

26*55 = 1430

$1,430

Spawn made a slight typo on this one......but....he was on the right track.....

12 * 8 * .25  = 24 yds^3

And the total cost =

$55 * 24  = $1320

[ I'll still give you 5 pts, Spawn......LOL!!!]
