Answer it is all about your visualization. Please see attachments. and compare SC to BCC and FCC in BCC and FCC an another plane exist at 100 position at half distance as in SC. therefore distance is half to SC in BCC and FCC. Use same reason for other planes. if another plane exist then distance will be half. if not exist distance will be same as in case of 110 and 111 plane of BCC and FCC.
