For thinkings

The glass cube dive into the aquarium, which has a length of 25 cm, width 20 cm and height of 30 cm. Aquarium water rises by 2 cm.

a) What is the volume of a cube?
b) How many centimeters measure its edge?

Correct result:

V =  1000 cm3
a =  10 cm

Solution:

V=25 20 2=1000 cm3
a=25 20 23=10 cm
