$A$ volume of $1 \ m^3$ is equal to

The dimensions of an aluminum block are $3.0 \, \text{inch} \times 4.0 \, \text{inch} \times 5.0 \, \text{inch}$. What is the mass of this block in grams? The density of aluminum is $2.7 \, \text{g/cm}^3$ and $1 \, \text{inch} = 2.54 \, \text{cm}$.

In the final answer of the expression $\frac{(29.2 - 20.2)(1.79 \times 10^5)}{1.37}$,the number of significant figures is

The number of significant figures in $0.00051$ is:
