PLEASE HELP!!
The width of a rectangular prism is five times its length. The height 5^2 is
times its width. If its length is 5^3
units, then the volume of the prism can be represented by 5 to the power of

5^13

The question wasn't very clear so this might be wrong.

Step-by-step explanation:

So the width of the rectangular prism is 5^3 * 5 = 5^4

The height of the prism is 5^2 * 5^4 = 5^6

The volume is 5^4 * 5^6 * 5^3 = 5^13

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
