volume of pit= 20x(6x100)x50=600000cm²

no. of planks= volume of pit/ volume of plank

=600000/1250

=480 planks

Vol.of one plank= 5 m*25 cm*10 cm= 500 cm*25 cm*10 cm= 125000 cubic.cm.

Vol.of pit= 20 m*6 m*50 cm=2000 cm*600 cm*50 cm= 60000000 cubic.cm.

No.of Planks= 60000000/125000

= 480 planks.

Hope this help you. :)
