Question

If the volume of a given cube 343 cubic inches, what is the surface area of the cube?

Answer 1

side length =
`\sqrt[3]{343}`

side length = 7

7 x 7 x 6 = 294

The surface area is 294 square inches

Hope this helps (: <3

Answer 2

SA = 294 in^2

Explanation:

The volume of a cube is

V = s^3

343 = s^3

Take the cube root of each side

7 =s

We know the side length is 7

The surface area of a cube is

SA = 6s^2

SA = 6 (7^2)

SA = 6(49)

SA = 294 in^2
