Question

1. 2.34 cm × 6 cm × 5.90 cm =
2. 15.7 ml + 0.134 ml + 135.2 ml =
3. 3.00×10³ g ÷ 1.5 × 10² ml =

Explanation:

Step1: Calculate the product in 32.

Multiply the lengths.
$2.34\times6\times5.90 = 2.34\times35.4=82.836$ $cm^{3}$

Step2: Calculate the sum in 34.

Add the volumes.
$15.7 + 0.134+135.2=151.034$ $mL$

Step3: Calculate the quotient in 46.

Divide the mass by the volume.
$\frac{3.00\times10^{3}}{1.5\times10^{2}}=\frac{3.00}{1.5}\times10^{3 - 2}=20$ $g/mL$

Answer:

1. $82.836$ $cm^{3}$
2. $151.034$ $mL$
3. $20$ $g/mL$
