The surface area (SA) of a cube can be written as:
SA = 6s²
From here we can write, the length of the side s as:

For cube with surface area of 1200 square inches, the side length will be:

inches
For cube with surface area 768 square inches, the side length will be:

inches
The difference in side lengths of two cubes will be:
Rounding to nearest tenth of an integer, the difference between the side lengths of two cubes will be 2.8 inches.
Answer:
B= 133° C= 47°
Step-by-step explanation:
As shows on the right it's 133°
A= 133°
c+a =180° -a
= 180° -133°
=47°
a and c complement each other and
b= a = 133°
a and b are vertical angles

Step-by-step explanation:
Step 1:
The area of the given circle is 240.48 π sq mm
We need to find the diameter of the circle
Step 2:
The formula for obtaining the area of any circle is π*r² where r represents the radius of the circle
We know that the diameter of circle is 2 times its radius.
Hence equating the formula of the area of the circle to the given value we can find its radius. Then multiplying the radius by 2 , we get the diameter.
Step 3 :
Using the above method , we have
πr² = 240.48 π
=> r² = 240.48 π / π = 240.48
=> r = √240.48 = 15.51 approximately
Hence the diameter of the given circle is 2 * 15.51 = 31.02 mm.
50 points I think cause 50•2=100 and 46•2=92 and 46/50 is equal to 92/100
