volume is width times length times height. 

so you have to do the opposite. divide the volume by the width and the height to find the length.

150/7.5 = 20
20/2=10
10=length :)

The length is 10.

Equation:
[tex]7 \frac{1}{2} [/tex] * 2 * l = 150

Multiply [tex]7 \frac{1}{2} [/tex] and 2:
15 * l =150

Divide both sides by 15:
l = 10
