The glass cube dives into the aquarium, which has a length of 25 cm, a width of 20 cm, and a 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 answer:

V =  1000 cm³
a =  10 cm

Step-by-step explanation:

$$\begin{gathered} a=25\text{cm} \\ b=20\text{cm} \\ c=30\text{cm} \\ x=2\text{cm} \\ V=a\cdot b\cdot x=25\cdot 20\cdot 2=1000{\text{cm}}^3 \end{gathered}$$
