Question

A metal cuboid of diamontion 22cm,18cm,6cm is melted a cast into to cylinder of height 21cm. 46 radius​

Answer 1

the volume of cuboid is (L×B×H)

so it will be (22×18×6)cm³

and volume of cylinder =>πr²h=22/7×46×46×21

=>πr²h=22×46×46×3

volume of cuboid = volume of cylinder

=>22×18×6×n=22×46×46×3(n=no. of cuboids)

=>2376n=139656

=>n=58.77

so n is 58

so 58 no. of cuboids are needed

mark as brainliest if it helps you

Answer 2

volume of cuboid=l×b×h

=> 22×18×6=2376cm³

Volume of cylinder=πr²h

22 × 46 × 46 × 21

7

=>139656cm²

no. of metal cubiods= vol. of cylinder/vol. of metal cuboid

139656÷2376

=>58.77 cuboid
