Question

area of cube and cuboid

Answer 1

Area of cube is 4s2 and area of Cupid is l×b×h l is  length  b is breadth h is height

Answer 2

$<b>$Answer :

$\color {red}\underline\textbf {There are two types of areas of Cube and Cuboid !}$

$\color {blue}\underline\textbf {a) Curved Surface Area}$

$\color {blue}\underline\textbf {b) Total Surface Area }$

Total Surface Area covers the whole area whereas, Curved Surface Area doesn't.

$\color {yellow}\textbf {Curved Surface Area of Cube =>}$

$= > 4 {l}^{2} \\ \\ where \: l \: is \: side \: or \: length. \\ \\ it \: includes \: the \: area \: of \: 4 \: phases.$

$\color {pink}\textbf {Total Surface Area of Cube =>}$

$= > 6 {l}^{2} \\ \\ where \: l \: is \: side \: or \: length. \\ \\ it \: includes \: the \:area \: of \: all \: the \: 6 \: phases.$

$\color {yellow}\textbf {Curved Surface Area of Cuboid =>}$

$= > 2(l + b)h \\ \\ where \: l = length \\ b = breadth \\ h = height \\ \\ it \: includes \: the \: area \: of \: 4 \: phases.$

$\color {pink}\textbf {Total Surface Area of Cuboid =>}$

$= > 2(lb + bh + hl) \\ \\ where \: l = length \\ b = breadth \\ h = height \\ \\ it \: includes \: the \: area \: of \: all \: the \: 6 \: phases.$

Tysm for the question :)
