are kinda nice because you just have to figure out one side
then multiply by six. Yeah one for each side of the cube.
Okay the surface area is side time side
times 6 so in this case we just divide 294
by six. Do that first to get 49
So thats the area of a side
and the formula for area length times height
and since it's cube we know length and height are
equal in length well the only number that will satisfy the stack is seven
thats 49 the length of one side is 7
and we know that the formula for the volume of a cube is
length times height times depth
in this case it's 7 times 7 times 7 and the volume is 343
also know that the inches argued that third power or cubed
so watch out for it. Looks like C is our answer.
