Answer:
X= 5/3
Step-by-step explanation:
A cube has all the sides equal.
A diagonal then acts as the hypotenuse of a face such that,
Sin 45° = Side/hypotenuse = Side/12.8 => Side = Hypotenuse * Sin 45 = 9.05 in
Volume = base*width*height = sides^3 (since all sides are equal) = 9.05^3 =741.22 in^3
To nearest tenth,
Volume = 741.2 in^3 {and correct answer is A)}
The box measures 6 by 5 by 4
Area of the top and bottom = 2* (6*5) = 60 square inches
Area of the sides = 2 * (5 * 4) = 40 square inches
Area of front and back = 2 * (6 * 4) = 48 square inches
60 + 40 + 48 = 148 square inches
