The rule of the volume of the triangular pyramid is
b is the area of its base
h is its height
Since the area of the base is 24.2 square feet, then
b = 24.2
Since its height is 5.2 feet, then
h = 5.2
Substitute them in the rule above to find the volume
Round it to the nearest tenth
The volume of the triangular pyramid is 41.9 cubic feet
