Answer 2

$\sf\large\red{\underline{\underline{Question}}}:$

• Find the side of a cube whose volume is 64 cm³

$\sf\large\red{\underline{\underline{Solution}}}:$

We know that,

$\red\bigstar\green{\underbrace{\underline{\boxed{\sf Volume_{Cube} = Side^3 }}}}$

$\large\succ\purple{\underbrace{\mathfrak{Substituting\:the\: value}}}:$

➨ Vol. of cube = side³

➨ 64 = side³

➨ side³ = 64

➨ side = 4

Therefore,

• Side of the cube is 4 cm.

$\sf\large\red{\underline{\underline{More\:to\:know}}}:$

• Vol. of Cuboid = LBH
• Vol. of Sphere = $\dfrac{4}{3}\pi\sf r^3$
• Vol. of Cylinder = πr²h
• Vol. of Cube = a³
• Vol. of Right Circular Cone = $\dfrac{1}{3}\pi\sf r^2h$
