  1. 4.5 in³    
  2. 6 in³    
  3. 6.75 in³    
  4. 1.5 in³    

hintHint:

The volume of a pyramid is given by 1 third cross times b a s e space a r e a space cross times space h e i g h t

The correct answer is: 1.5 in³


    Area of the base square is 1.5 × 1.5
    = 2.25 in2
    Volume of the pyramid = fraction numerator 1 over denominator 3 end fraction cross times 2.25 cross times 2
