Remark
A cube has six sides, all of them equal. The formula for 1 side is s^2. The formula for all six = 6s^2.
Step One
Find the surface area of the larger cube.
Area = 6 *s^2
s = 15
Area = 6 *15^2
Area = 6 * 225
Area = 1350
Step Two
Find the area of the smaller cube
Area = 6s^2
Area = 6 * 12^2
Area = 6 * 144
Area = 864
Step Three
Find the difference
Area1 - Area2 = difference
1350 - 864 = 486
The difference is area = 486 units^2 <<<<< Answer
There is a slightly shorter way. Take out the common factor of 6
Difference = 6 * (15^2 - 12^2)
Difference = 6 * (225 - 144)
Difference = 6 * (81)
Difference = 486
Answer:
Step-by-step explanation:
x = ¼y
y - x = 12
y - ¼y = 12
¾y = 12
y = 16
x = ¼y = 4
Answer: x=3/2

Answer:
The company must sell at least 2 shirts to break even.
Step-by-step explanation:
Cost:
The cost is given by the following equation:

Revenue:
The revenue is given by the following equation:

How many t shirts must the company sell to break even?
Breakeven point is when the revenue is the same as the costs. So



Multiplying everything by 3



Since you cant make a decimal value of shirts
The company must sell at least 2 shirts to break even.
