2. The surface area of a three-dimensional figure is the sum of the area measures for each of the figure's faces. Find the surface area of the cube shown below.
3 in.
s=6e2
3 In
Part 1: How many faces does the cube shown above have? (1 point)
Part II: Find the area of one face of the cube shown above. Show your work. (2 points)
Part III: Find the surface area of the cube shown above. Show your work. (2 points)

All cubes have six faces. Likewise, the cube shown above also has 6 faces.

Length of side of one face of cube = 3 inches

Area of one face :

= Side × Side

= 3 × 3

= 9 inch²

Therefore, the area of one face of this cube = 9 inch²

Area of cube = sum of the area of all faces

Then, the area of this cube :

Therefore, the area of this cube = 54 inches²

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
