Question

The rectangular room of a length 10m width and height cm for walls

Answer 1

Write the question properly

Answer 2

$\huge\green{\underline{Given :}}$

• $l = 10 m$
• $b = 10m$
• $h = 20m$

$\huge\green{\underline{Formula\: used :}}$

$\large\fbox\red{Vol. \:= \: l×b×h}$

$\large\fbox\red{Area \:= \: 2(l×b + b×h + h×l)}$

$\huge\green{\underline{Solution :}}$

${Vol. \:= \: l×b×h}$

=> ${Vol.\:= \:10\: m\: ×\:10\:m\:×\:20\:m}$

=> ${Vol.\:= \:2000\:m³}$ Ans.

${Area \:= \:2( l×b + b×h + h×l)}$

${=> Area = 2(10×10m²+10×20m²+20×10m²)}$

=> ${Area=2(100m² + 200m²+ 200m²)}$

=> ${Area\:= \:500\:m²}$ Ans.
