Flashcard 1: Find the missing length $l$ if $V=\frac{1}{6}$, $w=\frac{1}{2}$, and $h=\frac{2}{3}$.

Answer: $l=\frac{1}{2}$. Solve $\frac{1}{6} = l \times \frac{1}{2} \times \frac{2}{3}$; $l = \frac{1}{2}$.

Flashcard 2: What is the volume of a prism with $l=1\frac{1}{2}$, $w=\frac{2}{3}$, $h=\frac{1}{2}$?

Answer: $\frac{1}{2}$. Convert: $1\frac{1}{2} = \frac{3}{2}$, then $\frac{3}{2} \times \frac{2}{3} \times \frac{1}{2} = \frac{1}{2}$.

Flashcard 3: Find the base area: $l=\frac{5}{6}$ and $w=\frac{3}{10}$.

Answer: $\frac{1}{4}$ square units. Base area = length × width = $\frac{5}{6} \cdot \frac{3}{10} = \frac{15}{60} = \frac{1}{4}$.
