Answer 2

$\dag \: \underline{\sf Answer :}$

• Here we are given a cuboid whose Length (l) is 13 cm , Breadth (b) is 14 cm and Height (h) is 15 cm and we are asked to find the total surface area of cuboid. To calculate the total surface area of cuboid we will use the below given formula :

$:\implies\sf Total \: surface \: area \: of \: cuboid = 2 (Length \times Breadth + Breadth \times Height + Height \times Length)$

Now, just simply plug in the given values in above formula;

$:\implies\sf Total \: surface \: area \: of \: cuboid = 2(13 \times 14 + 14 \times 15+ 15\times 13)$

$:\implies\sf Total \: surface \: area \: of \: cuboid = 2(182 + 210+ 195)$

$:\implies\sf Total \: surface \: area \: of \: cuboid = 2(587)$

$:\implies \underline{ \boxed{\sf Total \: surface \: area \: of \: cuboid = 1174 \: {cm}^{2} }}$

$\therefore \: \underline{\textsf{The total surface area of the given cuboid is \textbf{1174 cm ^ \text2 }}}.$
