How many spherical lead shots of diameter 4 cm can be made out of a s

1.	How many spherical lead shots of diameter 4 cm can be made out of a solid cube of lead whose edge measures 44 cm.
Answer» Given, The radius of each spherical lead shot = r = 4/2 = 2 cm Volume of each spherical lead shot = 4/3 πr³ = 4/3 π 2³ cm³ Edge of the cube = 44 cm Volume of the cube = 44³ cm³ Thus, Number of spherical lead shots = Volume of cube/ Volume of each spherical lead shot = 44 x 44 x 44/ (4/3 π 2³) = 2541

How many spherical lead shots of diameter 4 cm can be made out of a solid cube of lead whose edge measures 44 cm.

Answer»

Given,

The radius of each spherical lead shot = r = 4/2 = 2 cm

Volume of each spherical lead shot = 4/3 πr³ = 4/3 π 2³ cm³

Edge of the cube = 44 cm

Volume of the cube = 44³ cm³

Thus,

Number of spherical lead shots = Volume of cube/ Volume of each spherical lead shot

= 44 x 44 x 44/ (4/3 π 2³)

= 2541
