The volume of candle holder is 30 inches cubed.
Step-by-step explanation:
Given,
Area of base = A = 15 square inches
Height of candle holder = H = 6 inches
As the holder is in shape of triangular pyramid, therefore,
Volume of candle holder = [tex]\frac{1}{3}AH[/tex]
Volume of candle holder = [tex]\frac{1}{3}*15*6[/tex]
Volume of candle holder = [tex]\frac{90}{3}=30\ in^3[/tex]
The volume of candle holder is 30 inches cubed.
