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:
0.4 × 3.2
Convert to fraction
0.4 = 4/10 = 2/5 & 3.2 = 32/10 = 16/5
0.4 × 3.2 = 2/5 × 16/5 = 32/25 = 1.28
Without conversion you press ur calculator and you get 1.28
Answer:
Step-by-step explanation:
angle 4 is congruent to angle 4 because they are alternate interior angles.
angle 5 is congruent to angle 3 because they are alternate interior angles.
angle 1+angle 2+angle 3 is equal to (=) angle 1+angle 2+angle 3
angle 1+angle 2+angle 3=180 degree(being sum of interior angles of a trianngle)
I have no idea what options but technically it’s possible to stack it an infinite amount of ways, TECHNICALLY, I’m not sure if it’s the answer you are looking for though good luck
