Hope I helped :)
Answer:h
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)}
<span>When we find the measurement of a light bulb's brightness, we're actually looking for its luminous intensity. Recall that the SI unit (standard unit) used to represent an object's luminous intensity would be candela. Hence, the answer would be D. candela.
