if the density of a 25cm cubed block of wood is 0.85g/ml calculate the wood's mass

To calculate the mass of the block of wood, we can use the formula for density:

\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]

Rearranging the formula to solve for mass:

\[
\text{Mass} = \text{Density} \times \text{Volume}
\]

Given:
- Density of the wood = \(0.85 \, \text{g/mL}\)
- Volume of the wood = \(25 \, \text{cm}^3\)

Since \(1 \, \text{cm}^3 = 1 \, \text{mL}\), the volume is also \(25 \, \text{mL}\).

Now, we can calculate the mass:

\[
\text{Mass} = 0.85 \, \text{g/mL} \times 25 \, \text{mL} = 21.25 \, \text{g}
\]

### Conclusion:
The mass of the 25 cm³ block of wood is **21.25 grams**.
