Answer:
Explanation:
The given solid is a square based pyramid. The formula for determining the volume of a square based pyramid is
Volume of pyramid = 1/3 × A×H
Where
A represents the area of the square.
H represents the height from the base to the apex of the pyramid.
Area of the square base is expressed as length × length
The length of the square base is 5 ft
Area of the square base is 5×5 = 25ft^2
Volume of the is 1/3 × 25× 7 = 58.33
Approximately 58.3 ft^3
