If one edge of a cube is 3 inches long, what is the surface area of the cube? a. 9 square inches b. 18 square inches c. 27 square inches d. 30 square inches e. 54 square inches

The correct answer option is E. 54 square inches.

Step-by-step explanation:

We are given that the length of one edge of a cube is 3 inches long and we are to find its surface area.

We know that the formula of the surface area of a cube is given by:

Substituting the given values in the above formula to get:

Surface area of cube 54 square inches

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
