Answer of this question

A metal cuboid of dimension 22cm×15cm×7.5cm.was melted and cast in to

pubg player

Given a metal cuboid of dimension length 22 cm breadth 15 cm and height is 7.5 cm

Then volume of cuboid

= 22 \times 15 \times 7.5 = 2475 c m^{3}

If we melt this cuboid and cast in the cylinder of height

14 c m

Then the volume of cuboid =volume of cylinder

Let

r

is a radius of a cylinder

Then volume of cylinder =

π r^{2} h = 722 \times r^{2} \times 14

∴ 722 \times r^{2} \times 14 = 2475

\Rightarrow r^{2} = 22 \times 142475 \times 7 = 56.25

\Rightarrow r = 7.5 c m
