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:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
