Question

find the volume and surface area of the cuboid of l=8m,b=4m and h=6.5m​

Answer 1

Question:-

Find Volume and Surface area of cuboid whose length is $8m$, breadth is $4m$and height is $6.5 m$

_____________________________

Given:-

Length= $8m$

Breadth=$4m$

Height= $6.5m$

_____________________________

To Find:-

Volume and Surface area of Cuboid.

_____________________________

Solution:-

$\implies$ Volume of Cuboid = $lhb$

$\implies$ Volume of Cuboid=$8×4×6.5$

$\implies$ Volume of Cuboid=$\boxed{208}$

$Now \: lets \: find \: surface \: area \: of \: cuboid ,$

$\implies$ Surface area of Cuboid=$2(lb+bh+hl)$

$\implies$ Surface area of Cuboid=$2[(8×4)+(4×6.5)+(6.5×8)]$

$\implies$ Surface area of Cuboid=$[32+26+52]$

$\implies$ Surface area of Cuboid=$\boxed{110}$

________________________________

Final Answers:-

$\implies$ Volume of Cuboid is $208$

$\implies$ Surface area of Cuboid=$110$

$\color{purple}\boxed{Formula \: Used}$

$\implies$Volume of Cuboid= $\boxed{length×breadth×height}$

$\implies$Total Surface Area of Cuboid=$\boxed{2[(length×breadth)+(breadth×height)+(height×lenght)]}$
