Question

find the area of wall whose length is 10O m breadht is 60 m and height is 15


please correct answer​

Answer 1

Answer:

Area: 100m x 60m =

${6000m}^{2}$

Formula

= length x breadth

Answer 2

☯ GivEn dimensions of a wall are 100 m × 60 m × 15 m.

☯ We have to find, Area of wall.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

★ Wall is in cuboidal shape.

⠀⠀⠀⠀⠀⠀⠀

$\dag\;{\underline{\frak{We\;know\;that,}}}$

⠀⠀⠀⠀⠀⠀⠀

$\star\;{\boxed{\sf{\purple{TSA_{\;(cuboid)} = 2(lb + bh + bl)}}}}$

⠀⠀⠀⠀⠀⠀⠀

${\frak{Here}} \begin{cases} & \text{Length = 100 m } \\ & \text{Breadth = 60 m } \\ & \text{Height = 15 m} \end{cases}$

⠀⠀⠀⠀⠀⠀⠀

$\dag\;{\underline{\frak{Putting\:values}}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 2(100 \times 60 + 60 \times 15 + 15 \times 100)$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 2(6000 + 900 + 1500)$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 2(8400)$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\pink{16800\;m^2}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore$ Total surface area of wall is 16800 m².

$\boxed{\underline{\underline{\bigstar \: \bf\:More\:to\:know\:\bigstar}}}$

• CSA of cuboid = 2h(l + b)

• Volume of cuboid = l × b × h

• CSA of cube = 4a²

• TSA of cube = 6a²

• Volume of cube = a³

Where,

• TSA = Total surface area
• CSA = Curved surface area
