If total surface area of a cube is $150 c m^{2}$ , find the edge.

Given: Total surface area of a cube $= 150$ cm $²$
Let $a$ be the side of a cube
Total surface area of a cube $= 6 a ²$

$\Rightarrow 150 = 6 a ²$
$\Rightarrow a ² = \frac{150}{6}$
$\Rightarrow a ² = 25$
$∴ a = 5$

If total surface area of a cube is 150 cm2, find the edge.

Given: Total surface area of a cube =150 cm²Let a be the side of a cubeTotal surface area of a cube =6a²⇒150=6a²⇒a²=1506⇒a²=25∴ a=5
