Explanation:

Step1: Recall volume formula

$V = l\times w\times h$

Step2: Substitute values

$V=5.750\times4.5\times1.50$

Step3: Calculate the product

$V = 5.750\times4.5\times1.50=38.8125$

Step4: Consider significant - figures

The least number of significant figures among the given measurements is 2 (in 4.5). So, we round 38.8125 to 2 significant figures. Rounding 38.8125 to 2 significant figures gives 39.

Answer:

39
