Question

the edge of a cube is 9cm. what is its surface area?

Answer 1

if the edge is 9 cm then one surface is 9*9. multiply that by the number of faces on a cube.

Answer 2

A cube has all 6 equal sides. Each of these sides has a surface area of (basexheight) = 9x9. There are 6 of these sides, so \[6\times9^{2}\]

Answer 3

Surface Area of a Cube = 6 a 2

6 (9)^2 = 486

Answer 4
