Question

Find the length of the side of a cube whose total surface area measures 600cm^2

Answer 1

We know that the total surface are of a cube = 6$a^{2}$

(where a is the side of the cube)

⇒ 600 = 6$a^{2}$

⇒ $\frac{600}{6}$ = $a^{2}$

⇒ 100 = $a^{2}$

⇒ a= 10 cm

Hence the side of the cube is 10 cm
