Answer:
A(0,-3) B (5,0) C(0,-7)D(5,-4)
Step-by-step explanation:
Answer:
V= 392 ft^3
Step-by-step explanation:
We know that the volume V of a pyramid is one-third the area of the base B times the height h.
If h= 8ft and areabase = 7ft x 7ft = 49 ft^2.
Then, the Volume V is:
V = areabase x height = 49 ft^2 x 8ft = 392 ft^3
So the solution is option D.
