Perhatikan gambar berikut!

L subscript p space end subscript k u b u s equals 5 cross times s squared L subscript p space k u b u s equals 5 cross times 8 squared L subscript p space k u b u s equals 5 cross times 64 L subscript p space k u b u s equals 320 space c m squared

s squared equals l u a s space s i s i space k u b u s space y a n g space d i a r s i r space s squared equals 8 cross times 8 s squared equals 64 space c m squared

L subscript p space end subscript g a b u n g a n equals L subscript p space k u b u s plus L subscript p space b a l o k minus s squared L subscript p space end subscript g a b u n g a n equals 320 plus 600 minus 64 L subscript p space g a b u n g a n equals 856 space c m squared
