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:

$V=25\cdot 20\cdot 2=1000{\text{cm}}^3$

$a=\sqrt[3]{25\cdot 20\cdot 2}=10\text{ cm}$
