The answer is y= 1 2/3 *steps in picture
Answer:
One way to see if two ratios are proportional is to write them as fractions and then reduce them.
Another way If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.
Step-by-step explanation:
Actually Welcome to the Concept of the Volumes.
Volume of cuboid= L*B*H
here, L=B=20cm and H=10cm
hence , we get as,
Volume = 20*20*10 => Volume = 4000 cubic cm.
hence the volume is ===> 4000 cm^3.
