Question

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 18 feet by 18 feet by 4 inches for a patio if the concrete costs $41.00 per cubic yard?

Answer 1

Any ideas?

Answer 2

$1476 is what I got

Answer 3

Did you change all the units to yards?

Answer 4

no XD

Answer 5

Workout the volume of the slab in yd^3

Answer 6

Or find the volume in cubic feet and divide that result by \[\frac{ 27~ft^3 }{ 1~yd^3 }\]

Answer 7

164?

Answer 8

I divided 108 by 27

Answer 9

Please show all steps of the work you've done, and please be certain to include the appropriate units of measurement.

Answer 10

18 feet by 18 feet by 4 inches becomes

(18 ft)(18 ft) ( [1/3] ft ) = ?

Answer 11

I typed that wrong sorry

Answer 12

All I see that's wrong with your latest result is that you haven't included units of measurement.

Answer 13

$164

Answer 14

108/27 multiplied by 41

Answer 15

41 being $41

Answer 16

Again I ask you to include units of measurement. $41 is incorrect; the correct version would be \[\frac{ $41 }{ yd^3 }\]

Answer 17

well i took the 108' and divided it by 27' to get the cube yards. I then multiplied this by $41- the price of a cubic yard of concrete

Answer 18

toss out that $164.

Multiply 108 yd^3

by
\[\frac{ $41 }{ yd^3 }\]
and simplify your result. What does this result represent?

Answer 19

its not 108 yd^3 it is 108'^3

Answer 20

I have to go. Thanks for the help
