Answer:

6.24

Bill has a container that is shaped like a cube. He uses 125 cubes with a side length of 1 inch to fill the container completely
Annette [7]

Answer:

5 inches

Step-by-step explanation:

Given

Length of a cube = 1 inch

Required

Determine the edge length of the cube

If the container can take 125 cubes, then that's the volume

So:

Volume = 125in^3

Volume of a cube is calculated as thus;

Volume = Length^3

This gives;

Length^3 = 125

Take cube root of both sides

Length = \sqrt[3]{125}

Length = 5

Hence, the length is 5 inches

To take a taxi , it cost $3.00 plus an additional $2.00 mile traveled. you spent exactly $20 on a taxi, which includes the $1tip
forsale [732]
Let's break it down. 
You spent $20. Plus the $1 tip. 
20 - 1 = 19 
$19 is how much you spent without the tip
The cost for the taxi ride itself is $3
19 - 3 = 16
$16 is how much you spent without the ride cost + tip
You spent $2 for every mile traveled.
16/2=8 

You traveled 8 miles
