Resulting 4429

What will be the resulting volume V, if we mix liquids with volumes of 3hl and 200 cubic dm
A) V = 0.32 cubic meters
B) V = 0.50 m cubic
C) V = 23hl
D) V = 5m cubic

Correct answer:

V =  0.5 m³

Step-by-step explanation:

$$\begin{gathered} V_1=3\text{hl}\to {\text{m}}^3=3:10{\text{m}}^3=0.3{\text{m}}^3 \\ {V}_2=200{\text{dm}}^3\to {\text{m}}^3=200:1000{\text{m}}^3=0.2{\text{m}}^3 \\ V=V_1+V_2=0.3+0.2=\frac{1}{2}=0.5=0.5{\text{m}}^3 \\ B \end{gathered}$$
