Answer:

Option (4)

Step-by-step explanation:

To calculate the volume of a pyramid we use the formula,

V = [tex]\frac{1}{3}(\text{Area of the base})(\text{Height of the pyramid})[/tex]

Area of the square base = (Side)²

                                         = (6)²

                                         = 36 square ft

Height of the pyramid 'h' = [tex]\sqrt{l^{2}-(\frac{\text{Side length of the base}}{2})^{2}}[/tex] [By Pythagoras theorem]

h = [tex]\sqrt{5^{2}-3^{2}}[/tex]

h = [tex]\sqrt{16}[/tex]

h = 4 ft

Therefore, volume of the given pyramid = [tex]\frac{1}{3}(36)(4)[/tex]

                                                                   = 48 cubic ft

Option (4). 48 ft³ will be the answer.
