Answer:
5000 ft³
Step-by-step explanation:
You want the volume of the larger of two similar pyramids whose edge length ratio is 10:1, when the volume of the smaller is 5 ft³.
Similar volumes
The ratio of the volumes of similar figures is the cube of the ratio of their scale factor.
V/(5 ft³) = (10/1)³
V = (5 ft³)(10³) = 5000 ft³
The volume of the larger pyramid is 5000 ft³.
