Question

I want step by step solution....​

Answer 1

Answer:

Let the number of lead shots be x

Volume of lead in the rectangular solid =(66×42×21)cm3 

Radius of a lead shot =24.2cm=2.1cm

Volume of a spherical lead shot =34π×(2.1)3cm3

Volume of x spherical lead shots =(34×722×(2.1)3×x)cm3

Volume of x spherical shots = Volume of lead in rectangular solid

(34×722×(2.1)3×x)=66×42×21

⇒x=4×22×(2.1)366×42×21×3×7⇒x=1500

∴ Number of lead shots=1500

this is answer
