Mars is on average about 225 million km from Earth (the distance varies greatly, depending on both planets' position in their orbits). That translates to an average distance of 12.5 light minutes. It can vary from about 4 minutes to 24 minutes, depending on Mars's current distance from Earth.
Below are some concrete prices to help you determine your new concrete foundation cost. 1  Concrete is typically measured by cubic yards (3âx3âx3â). 2  An average cost for a cubic yard of concrete is $75 to $125, depending on how much is needed and local prices.

Add the footer and foundation cubic feet together to get 2,600 cubic feet of concrete necessary to pour the footer and foundation wall. Now you will need to convert the cubic feet into cubic yards in order to estimate the number of cubic yards of concrete necessary for the job.Do this by dividing the total feet by 27 (2,600 cubic feet divided by 27 equals 96 cubic yards of concrete to pour the foundation).The price of concrete ranges from 80 to 100 dollars per yard, as of 2011. Call you local concrete provider to get a per yard price.o this by dividing the total feet by 27 (2,600 cubic feet divided by 27 equals 96 cubic yards of concrete to pour the foundation).
