<span>B: To make the box, we need 2 triangular ends,
and 3 rectangular sides. Side the volume = 3240
and the height = 30, the area of each base (end) = 108.
The sides have areas of 30 x 42 = 720, and 30 x 15 = 450,
and there are 2 of those. So total area = 108 + 108 + 720 + 900 = 1836 cm^2

Add the numbers and divide by 5 to get a mean of 6.4
8 - 6.4 = 1.6
4 - 6.4 = -2.4
7 - 6.4 = 0.6
8 - 6.4 = 1.6
5 - 6.4 = -1.4
Add the absolute value of each: 1.6 + 2.4 + 0.6 + 1.6 + 1.4 = 7.6
Divide by 5 = 1.52

Answer: the cube root of 512 is 8.
Step-by-step explanation:
First divide 512 and take the least factors as I have shown,
512= 2×2×2×2×2×2×2×2×2
Now, make the triple twins of these factors,
(2×2×2)(2×2×2)(2×2×2)
Now, take one number from each pair and multiply them,
2×2×2=8
Therefore, the answer of the cube root of 512 is 8.
