Answer:
1944 Inches Squared
Step-by-step explanation:
Surface area Formula for a Cube:
[tex]A = 6a^2[/tex]
The "edge", which is also the side, is 18 inches.
[tex]a = 18[/tex]
Solve the formula.
[tex]A= 6a^2 = 6(18)^2 = 6 * 18^2\\18^2 = 324\\324 * 6 = 1944\\A=1944[/tex]
The cube's surface area should be 1944 square inches.
