Answer:
26.25
Step-by-step explanation:
you just need to count dots on the pencil
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
Okay so subtract 50 from both sides and you would get 360=90x and then divide each side by 90 and you would get x= 4 so it took 4 hours
