Question

The TSA of cube is 726cm square. Find the length of its edge? ​

Answer 1

$tsa = 726 \\ 6 {a}^{2} = 726 \\ {a}^{2} = \frac{726}{6} \\ {a}^{2} = 121 \\ a = \sqrt{121} \\ a = 11 \\ edge \: of \: cube = 11cm \\ hope \: it \: helps$

Answer 2

given,

TSA of cube = 726

6a^2 = 726

a^2 = 121

a = 11 cm

therefore length of its edge is 11 cm
