Question

The largest cone is curved out from one face of solid cube of side 21 cm. Find the

volume of the remaining solid. ​

Answer 1

$volume \: of \: cube \: =$

$a {}^{3} = 21 {}^{3} cm {}^{3}$

$< br > volume \: \: of \: cone \: =$

$1 \div 3 \times 22 \div 7 \times 21 \div 2 \times 21 \div 2 \times 21$

$< br >$

$= 441 \times 11 \div 2cm {}^{3}$

$< br >$

$v = 21 \times 21 \times 21 - 441 \times 11 \div 2$

$< br >$

$= 6835.5cm {}^{3}$
