Respuesta :
The lateral area of a cube is the area of four of its sides combined. The equation for a cube's lateral area would be A=s^2*4
9=s^2*4 (plug in what we know)
9/4=s^2 (divide by 4)
s=3/2 (square root both sides)
9=s^2*4 (plug in what we know)
9/4=s^2 (divide by 4)
s=3/2 (square root both sides)
