Answer:

$V=343\,\,cm^3$

Explanation:

Recall that fractional exponents are other form of representing roots.

In our case, the formula for the volume of the cube in terms of area of a face, is also written as:

V=A^(3)/(2) =(√(A) )^3

which for the case of a cube with face area of 49 cm^2 becomes:

$V=(√(49) )^3=7^3=343\,\,cm^3$
