yan [13]

Answer:

1944 Inches Squared

Step-by-step explanation:

Surface area Formula for a Cube:

$A = 6a^2$

The "edge", which is also the side, is 18 inches.

$a = 18$

Solve the formula.

$A= 6a^2 = 6(18)^2 = 6 * 18^2\\18^2 = 324\\324 * 6 = 1944\\A=1944$

The cube's surface area should be 1944 square inches.
