Answer:
A: 1779.2 cm^2
Explanation:
Oh boy. Okay so the surface area of the cube.
14x14 is 116 cm.
Multiply 116 by 6 (because there are 6 square sides) which gives you 696 cm
For the can shape: (Cylinder lol)
The radius of the circular sides is 6.
Area of a circle is pi(r)^2
pi(6)^6
=18.8^2
=353.44 cm
multiply by 2 because there are 2 sides
353.44 x 2= 706.88 cm
add that to 696
=1402.88 cm
FINALLY: the last part. We need the circumference and the height of the cylinder.
We know that the height is 10 cm.
Use the circumference equation and we see that is is 37.69 cm
multiply by 10
376.9 cm
Add to the rest
1779.2 cm^2
Have a nice day. Im gonna go rest my brain L /\/\ /\ O
