The surface area cube is 96 square units what is the edge lenght

4 units

Step-by-step explanation:

We know the surface area of a cube is equal to:

Since we know what the surface area is, we simply need to solve for s:

both equations and proportions are better.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
