How to find the volume of a prism Flashcards - GRE Quantitative Reasoning

Remember, the formula for the volume of a rectangular prism is width times height times length:

$V=w\cdot h\cdot l$

Now, let's solve the word problem for each of these values. We know that . If length is double the width, then the length must be 6 units. If the height is two-thirds the length, then the height must be 4:

$6\cdot \frac{2}{3}=4$

Multiply all three values together to solve for the volume:

$V=w\cdot h\cdot l$

$V=3\cdot 4\cdot 6$

The volume of the rectangular prism is units cubed.
