The surface area of a jumbo sized rubiks cube is 294 square inches. Find the length of a lateral edge.

7 inches

Step-by-step explanation:

Each surface is square.

And area of square is (side) ^2

That means, total surface area will be 6 * (side) ^2

From question,

294 = 6 * (side) ^2 (Surface area given)

=> 294 : 6 = (side) ^2

=> 49 = side^2

=> √49 = side

=> 7 = side

So, length of edge of cube is 7

7 inches

Step-by-step explanation:

The surface area of a cube is denoted by: A = 6s², where s is the side length.

Here, we know that A = 294, so plug this into the formula to solve for s:

A = 6s²

294 = 6s²

s² = 49

s = √49 = 7

Thus, the answer is 7 inches.
