What is the surface area of the cube? cube with length, width, and height labeled 7 millimeters

A. 42 mm²

B. 49 mm²

C. 294 mm² D.

1764 mm²

To find the surface area of the whole cube, you need to first find the area of one side.

So one side is just a square with length and width of 7mm. So the area would be 7 x 7 = 49mm².

Since there are 6 sides on a cube, multiply this area by 6 to give you the whole surface area of the cube.

49 x 6 = 294mm²

One side will be 7x7 because its a square. there are 6 sides so 49x6=

294 mm2
