Alice’s chicken coop (cage) has a total volume of 742 cubic feet (ft3). Use the fact that 1 foot is approximately equal to 0.3048 m to convert this volume to m3.

21.01 cubic metres

Step-by-step explanation:

We have to find the value of 1 cubic foot and then convert to cubic metre.

1 foot = 0.3048 m

1 cubic foot = = 0.02832 cubic metre

A volume of 742 cubic foot will therefore be:

742 * 0.02832 = 21.01 cubic metres

The volume in cubic metres is 21.01 cubic metres
