To find the surface area of the cube using the formula, you would substitute in 2 1/2 for the length of the side.
SA = 6 x 2.5 x 2.5
SA = 37.5 ft.²
You are finding the area of one face (2.5 x 2.5) and multiplying it by six because there are six groups of this.
Do you have the answer options? Sorry, can't answer without them ):
2.5=2x
2.5/2=x (of course when dividing by a fraction you multiply by the reciprocal so it would be 5/2*2/1
x=5/4
Answer:
angle 7 is congruent to angle 6 because both are vertical angles and vertical angles are congruent to one another
angle 6 and angle 10 are congruent because both are corresponding angles and corresponding angles are congruent
thus angle 7 is congruent to angle 10 because vertical angles
