CREATE TABLE table_29280 ("Position" FLOAT, "Building" TEXT, "City" TEXT, "Height" TEXT, "Number of floors" FLOAT, "Completion" FLOAT)

If the number of floors is 70, what is the height?
SELECT "Height" FROM table_29280 WHERE "Number of floors" = '70'
SELECT "Height" FROM "table_29280" WHERE "Number of floors" = '70'
