correct

ok thx Steve

To calculate the amount of soil that a rectangular garden planter can hold, you need to find the volume of the planter.

The formula for calculating the volume of a rectangular shape is:
Volume = Length x Width x Height

In this case, the length of the planter is 4 feet, the width is 1.5 feet, and the height is also 1.5 feet.

Plugging in these values to the formula, we have:
Volume = 4 feet x 1.5 feet x 1.5 feet

Simplifying this calculation:
Volume = 9 cubic feet

The rectangular garden planter can hold 9 cubic feet of soil.
