first lets convert m to mm.we know, 1 m=1000 mm. 5 m =5000 mm and 8m=8000mm. Now, no.of paving slab = area of flags /area of slab . =5000 X8000/450 x 450. =197.5 = 197 slabs.

6 x 50 = 300
-100

50-50 methods = 0
50 plus 50 plus 50 equal 150
% rate: = 50% = 50/100 * 100% = 50/1 * 1% = 50%
50 cubed = 503 = 50 * 50 * 50 = 150000
