What is the surface area of a cube witha side lebgth of 4 inches

ANWSERS
o 12 in2
o 48 in2
o 64 in2
o 96 in2

D. 96

Step-by-step explanation:

1. find the area of one side

2. multiply this number by 6 because a cube has 6 sides

the correct option is b

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
