Some people feel that a lap and a length are the same thing. They will use the terms interchangeably. Competitive swimmers do not often talk about lengths, but when they do they usually mean one complete length of the pool. As such, a lap generally refers to two lengths. For example in a 25 yard pool, a mile is ~35 laps, or ~70 lengths.
Webster's II New College Dictionary uses the following definition for lap in regard to pools: "2.b. One complete length of a straight course, as in a swimming pool."

20 lengths of a 25 meter pool, or 10 lengths of a 50 meter pool. Some people refer to a lap as one pool length, while others refer to a lap as down and back (2 lengths). I haven't found which one is the correct terminology, but the term length has only one meaning (for the particular pool that you are using).
One length of an Olympic size swimming pool is 50mtrs or 164.041 feet, so a lap (2 lengths) would be 328.082 feet
70.4 laps. 25yds is 75 feet. (5280ft/mi)/75ft=70.4. If a lap is one length then 70.4 laps. If a lap is two lengths, i.e., up and back then its 35.2 laps.
