What is the surface area of a cube whose edges are 11 inches long?
2 answers:
Surface area is the total area of the surface. A cube has 6 surface, and each surface is the same. Each surface is a 11 by 11 square. Therefore there will be 6 11in. x 11in. surfaces. The math would be 11x11x6 =726.
Answer:
726 in²
Step-by-step explanation:
The surface area of a cube is the area of each side of the cube multiplied by 6 (since the cube has 6 sides).
To know what is the area of each side, the formula is A= l² where l is the length. Therefore we would have that the area is 11²=121.
Now we are going to multiply this number by 6 to find the surface area, SA = 121 x 6 = 726 in²

Step-by-step explanation:
The first one 'cubes' the denominator AND the numerator:
(-2/5)^3 = -2/5 * -2/5 * -2/5 = -8/125
The second one 'cubes' only the denominator:
-2/5^3 = -2 / (5 * 5 * 5) = - 2 / 125
It’s dividing by a factor of 10. So 30 divided by 10=3. You then do the same thing for the height. 300 divided by 10=30. The answer is 30.
