Length = 2 ft
Width = 2 ft
Height = 6 ft
Volume of the square based pyramid = ⅓ × length × Width × height
= ⅓ × 2 × 2 × 6
= ⅓ × 24
= 8 cubic feet
Cost of soil per cubic foot = $0.78
Therefore,
Cost of filling the planter with soil = Volume of the square based pyramid × Cost of soil per cubic foot
= 8 × $0.78
= $6.24
