Can someone take the time to answer this for me? I try to turn the feet into inches and then all the inches into feet but it doe
Mumz [18]
To find the equation, we first need to change the unit as you did correctly:

1 feet = 12 inches

In this case,let's turn the unit of depth to feet:

4÷12
= 1/3 feet

Then we can find the volume in inches:

1/3×162×6
=54×6
=324 ft^3

Therefore the answer is B.324 ft^3 .

Hope it helps!
