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 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
