Step-by-step explanation:
a=7
=6a^2
=6×(7)^2
=6×49
=294
Answer:
Surface area of the cube = 294cm^2
A cube has the same side lengths for every side
Surface area of one face is length * length
7 * 7 = 49cm^2
A cube has 6 faces
49 * 6 = 294cm^2
5.692 × 103.
C would be your answer as the formula for the volume of a cone is pi*r²*h/3
