Answer:
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
Answer:
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 :
[tex]\frac{150}{6} in^2=25\,\,in^2[/tex]
Then, if the area of each square face is 25 [tex]in^2[/tex], then, recalling that the area of a square of side "b" is:
[tex]Area_{square}=b^2[/tex]
then:
[tex]b^2=25\,\,in^2\\b=5\,in[/tex]
