Find Side Length HF in a Cuboid with Volume 60 cm³

To find the length of side HF, follow these steps:

• Step 1: Identify known values - Volume $V = 60 \, \text{cm}^3$, given side lengths are 4 cm and 5 cm.
• Step 2: Apply the volume formula for a cuboid: $V = l \times w \times h$, with two sides known as 4 cm and 5 cm.
• Step 3: Set up the equation using $x$ as the unknown side: $4 \times 5 \times x = 60$.
• Step 4: Solve for $x$:
  $20 \times x = 60$
  Divide both sides by 20: $x = \frac{60}{20} = 3$.

Thus, the length of side HF is $3 \, \text{cm}$.
