The surface area of a cube is 96 square inches. What is the length of an edge of the cube, in inches?

Bezzdna [24]

Answer:

16 inches

Step-by-step explanation:

A cube has 6 sides and to find the surface area you would multiply one side by 6, or add the six sides together. So instead, to find the length of one side, you divide the surface area, 96, by 6 to get 16.

Hope this helps you :)

Cheyenne drove 3000 miles in 75 hours. At this rate, how long will it take her to drive 4000 miles?

lyudmila [28]

Set up a proportion:
$\frac{3000}{75}$ = $\frac{4000}{x}$
To solve cross multiply:
3000x=300000
divide both sides by 3000:
3000x/3000=300000/3000
x=100

It will take her 100 hours to drive 4000 miles assuming she continues to travel at this rate.
