Answer 1

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

ᴅɪᴍᴇɴsɪᴏɴ ᴏғ ʜᴀʟʟ = ( 30 × 17 × 6 )ᴍ³

sᴘᴀᴄᴇ ʀᴇϙᴜɪʀᴇᴅ = 5 ᴍ³

Pᴇʀsᴏɴs ᴄᴀɴ sɪᴛ = $\mathtt{\frac{(30\times17\times6){m}^{3}}{5{m}^{3}}}$

—» 612 .

Answer 2

V = volume of hall = 30 × 17 × 6 m³

V² = 5m³

Number of people can sit = V¹/V²

=30×17×6÷5

=6×17×6

=612
