a=5 in

Step-by-step explanation:

surface area A=6a^2 ( it is a cube all edges are equal)

a=√A/6=√150/6=√25=5

The length of the side of one side of a square face is 5 in, which agrees with the second answer in the list of options.

Step-by-step explanation:

Recall that a cube has 6 equal faces, therefore, the area of each face must be :

Then, if the area of each square face is 25 , then, recalling that the area of a square of side "b" is:

then:

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative
