Answer 2

Question:

• Find the total surface area of a cardboard box of length 0.5, breadth 2.5 cm and height 15cm

Given:

• Length = 0.5cm
• Breadth = 2.5cm
• Height = 15cm

To find: 

• Total surface area of closed cardboard box?

Required Formula:

$\begin{gathered}\begin{gathered} {\color{orange}\bigstar}\; \underline{\boxed{\frak{{Total\:surface\:Area_{\;(cuboid)} = 2(lb + bh + hl)}}}}\\\end{gathered}\end{gathered}$

Solution:

• Let's Solve

$\begin{gathered}\begin{gathered}\bf{\dag}\; \large{\underline{\frak{ \color{navy}{Substituting\:the\:given\:values,}}}}\\ \\ \\:\implies\sf 2(0.5 \times 2.5 + 2.5 \times 15 + 15 \times 0.5)\\ \\ \\ :\implies\sf 2(1.25 + 37.5 + 7.5)\\ \\ \\ :\implies\sf 2(46.25)\\ \\ \\:\implies{\underline{\boxed{\frak{ \pmb{ \color{pink}{92.5\:cm^2}}}}}}\pink\bigstar\\ \\\end{gathered}\end{gathered}$

$\therefore{\underline{\sf{ Total\:surface\:area\:of\:cuboid\:is\: \textsf{\textbf{92.5cm²}}.}}}$
