The surface area of a cube is 600 square inches. What is the area of one of its faces? A. 6 square inches B. 36 square inches C. 75 square inches D. 100 square inches

Respuesta :

check the picture below.


recall that a cube sides are all equal in length, and it's really just 6 squares stacked up to each other at the edges.


so if 600 is the total area of those 6 squares, then just for one is 600/6 in².

Answer:  D. 100 square inches

Step-by-step explanation:

As you know, a cube has 6 faces, and each face is a square, and the 6 faces are equal.

then, the total surface area of the cube is equal to 6 times the surface area of one of the faces:

6*f = 600 in^2

then the surface area of one face is:

f = (600/6) in^2 = 100 in^2

Then the correct option is D
