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

times 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.
