Question

find the surface area of a cube with the length of 2/3

Answer 1

Answer:

2 2/3 u^2

Step-by-step explanation:

Since it is a cube, we can find one area and multiply it by 6 (6 sides on a die).

(2/3)^2 = 4/9

4/9 x 6 = 24/9 or 2 2/3

Answer 2

Answer:

$surface \: \: \: \: area \: \: = 2.669$

Step-by-step explanation:

$\frac{2}{3} = 0.667 \\ surface \: \: \: area = 6 {a}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6 \times {0.667}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2.66933$
