Step-by-step explanation:
Lengh of one plank =2m
=200 cm
Breadth (b)=25 cm
thickness (h)=8 cm
∴
Volume of plank
=
l x b x h = 200 x 25 x 8 cm³
=
40000 cm ³
Length of block (l)=5m =500 cm
Width (b)=70 cm
and thickness (h)=32 cm
∴
Volume of block
=
500 x 70 x 32 cm³
Number of planks
=
Volume of block
Volume of plank
=
500 x 70 x 32
= 1120000
=1120000 / 40000
=28
