Answer:
1944 Inches Squared
Step-by-step explanation:
Surface area Formula for a Cube:

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

Solve the formula.

The cube's surface area should be 1944 square inches.
7
When you do 27 times x squared times z all over -3, then times that by x squared times z to the sixth power, you get -9x^4z^7
To find the length of the base, we have to understand that area of triangle:
Base x height/2
Therefore we would multiply the area by 2 and divide by 4 to find the answer:
24x2/4
=48/4
=12
Therefore the answer is 12m.
