HI Tori,

You didn't tell us the shape of the base but I am going to assume it is a rectangle and that you are working with a rectangular prism. The volume of a prism is the area of the base times the height and since the area of a rectangle is the length times the width, the volume of your rectangular prism is

\[\mbox{length } \times \mbox{ width } \times \mbox{ height} = 105 \mbox{ cubic feet.}\]

or

\[10 \times \mbox{ width } \times 7 = 105 \mbox{ cubic feet.}\]

What is the width?
