how to calculate the surface area of a cube with a volume of 343 cubic feet?

294 square feet

Step-by-step explanation:

If the volume is one  side  at the 3rd power, then  If we know the volume, we calculate   the cubic root of 343  that is 7

So 1 side =7

The cube has 6 faces

1 face of the cube is 7*7=49

Six faces =

49*6= 294

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
