To find the surface area of the cube using the formula, you would substitute in 2 1/2 for the length of the side.

SA = 6 x 2.5 x 2.5
SA = 37.5 ft.²

You are finding the area of one face (2.5 x 2.5) and multiplying it by six because there are six groups of this.

keisha drove 380 miles using 14 gallond of gas. At this rate, how many gallons of gas would she need to drive 418 miles?

pychu [463]

14gallons=380miles

14/380=<span>0.03684210526gallons/mile
</span>
418*<span>0.03684210526=15.4gallons
</span>
or you could cross multiply

14gallons=380miles
x gallons=418miles

$\frac{14}{380} = \frac{x}{418}$

380x=5852
divide both sides by 380
x=15.4 gallons
