A cube has a volume of 64 cubic units. What is its surface area

Alona [7]

The volume of a cube is length x width x depth. In a cube all would be equal therefore.

x^3= 64 
x =4 
The area in square feet of one side would then be length x width 

There are 6 sides so the surface area of the cube would be 

(4)(4)(6) = 96 square feet

Alisiya [41]

s -> no: of standard CD players sold

p -> no: of portable CD players sold.

Profit Per Standard CD player=72$

Profit per Portable CD player =90$

Target Amount =360$

In short: The combined sales of Both the CD player's must exceed or atleast become equal to 360$ to acquire the target.

Thus; the inequality can be stated as:

 72(s) + 90(p) ≥360

-> 36(s) + 45(p) ≥180

-> 12(s) +15(p) ≥ 90

 _______________

->| 4(s) + 5(p) ≥ 30 |
