$\bf{\underline{Question:-}}$

how many balls can be made out of a cube of lead whose edge measures 11 cm each ball being 1cm in diameter.

$\bf{\underline{Solution:-}}$

• Dimension of solid lead cube

◆ Edge of cube = 11cm

◆ Volume of cube = a³ = 11³ =

◆ Volume of cube (ᵛ1) = 11 × 11 × 11 = 1331 cm³

• Dimensions of each spherical ball

◆ Diameter (d) = 1cm

◆ Radius (r ) = d/2 = 1/2 = 0.5 cm

• Volume Of Each Spherical Ball (ᵛ2)= 4/3πr³

$\rm → V_2= \frac{4}{3}×\frac{22}{7}×0.5^3$

$\rm → V_2=\frac{4}{3}×3.14×0.125$

$\rm → V_2 = 1.33 × 3.14 × 0.125$

$\rm → V_2= 0.5233$

• Number of spherical balled made by solid cube "x"

→ x = ᵛ1 / ᵛ2

→ X = 1331 ÷ 0.5233

→ x = 2544.933

$\bf{\underline{Hence:-}}$

• 2545 balled were required approximately.
