Rectangular 6030

The aquarium has a rectangular base of 0.5 m × 0.3 m. By immersing the irregular body, the level enters by 3 cm. Calculate the volume of the body.

Correct answer:

V =  4.5 l

Step-by-step explanation:

$$\begin{gathered} a=0.50\cdot 10=5\text{dm} \\ b=0.3\cdot 10=3\text{dm} \\ c=3/10=\frac{3}{10}=0.3\text{dm} \\ 1d{m}^3=1l \\ V=a\cdot b\cdot c=5\cdot 3\cdot 0.3=4.5\text{l} \end{gathered}$$
