Answer:
30 cubic feet
Step-by-step explanation:
Here we are given the volume of rectangular pyramid as 90 cubic feet as we are required to find the volume of rectangular prism.
For that we need to use the theorem which says that
the volume prism is always one third of the volume of the pyramid . Whether it is rectangular of triangular base. Hence in this case also the volume of the rectangular prism will be one third of the volume of the rectangular pyramid.
Volume of Rectangular prism =
* Volume of rectangular pyramid
=
* 90
= 30

Answer:
15 hours
Step-by-step explanation:
Given:
Fernell's speed
mph
Dabney's speed
mph
Denote:
- distance covered by Fernell
- distance covered by Dabney
- Fernell's time
- Dabney's time
1. If Fernell drove for 3 hours longer than Dabney, then his time is 3 hours more than Dabney's time and

2. If Fernell covered 18 miles less than Dabney, then

Use formula 

Subtract from the first equation the second equation and equate it to 18:


I believe the answer is 25% because 6/24 is 1/4 and 1/4= 25%
