Question

If the total surface area of a cube is 50/3 m2

. Find its side.​

Answer 1

Answer:

Total surface area formula is $6a^2$,

$6a^2=\frac{50}{3}\\=a^2=\frac{50}{3}*\frac{1}{6}\\=a^2=\frac{25}{9}\\=\sqrt{a^2}=\sqrt{\frac{25}{9}}\\ =a=\frac{5}{3}$

Therefore, the length of the side of the cube is $\frac{5}{3} m/s^2$.
