We have to determine the number of cubic centimeters in 5.78 cubic yards.
Since there are 764555 cubic centimeters in 1 cubic yard.
To convert cubic yard to cubic centimeters, we have to multiply the given cubic yards with 764555.
Therefore, 5.78 cubic yards
=
= 4419127 cubic centimeters
Therefore, there are 4419127 cubic centimeters in 5.78 cubic yards.
