We know that
volume of a cuboid=length*width*height
in this problem
we have
volume=(18 cm)³
so
volume=18*18*18 cm³
the dimensions of the cuboid are
length 18 cm
width 18 cm
height 18 cm
18 cm x 18 cm x 18 cm
4:
5+4, 4+5, 6+3, 3+6
There is a total amount of 36 different ways so:
4/36 = 1/9 = 11.11%
Let x be the weeks worked on building the road
13=(1/2)x
13*2=x
26 days=x
In the duration of 26 weeks, the road should be built.
Hope I helped :)
