One of the important question for the board exam class 10 from mensuration chapter.

This question is from r d sharma class 10 maths.

chapter-16 question number-11 maths r d sharma,mensuration.

In this question we have to find spherical lead shots of diameter 4 cm can be made out of a solid cube of lead whose edge measures 44 cm

Given,

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

Volume of each spherical lead shot = 4/3 Ï€r3 = 4/3 Ï€ 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 Ï€ 23)

= 2541
