Practice Problems on Volume of a Rectangular Prism
Use the formula for the volume of a cylinder as shown below.
Volume = (2)(5)(3)= 30
$$ volume = length \cdot width \cdot height \\ 30 = 5 \cdot 2 \cdot width \\ 30 = 10 \cdot width \\ width = \frac{30}{10} = 3\text{ "} $$
$$ 5^3 = 125 \\ volume = length \cdot width \cdot height \\ 125 = 5 \cdot 5 \cdot 5 \cdot 5 $$
$$ \\ volume = length \cdot width \cdot height \\ V = 2 \cdot 3 \cdot 6 = \color{red}{36 \text{ in}^3 } $$
$$ volume = length \cdot width \cdot height \\ V = 1 \cdot 3 \cdot 7 = 21\text{ in}^3 $$
