Answer 2

Question:

• Find the total surface area of a cardboard box of length 0.5m, breadth 25 cm and height 15cm

Answer:

• The total surface area of cardboard box is 4,750cm²

Step-by-Step Explanation:

Given:

• Length = 0.5m= 50cm
• Breadth = 25cm
• 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

$</p><p>\begin{gathered}\begin{gathered}\bf{\dag}\large{\underline{\frak{ \color{indigo}{Substituting\:the\:given\:values,}}}}\\\\\\:\implies\sf 2(50 \times 25 + 25 \times 15 + 15 \times 50)\\\\\\:\implies\sf 2(1250 +375+ 750)\\\\\\:\implies\sf 2(2375)\\\\\:\implies{\underline{\boxed{\frak{{4750\:cm^2}}}}}\pink\bigstar\\\\\end{gathered}\end{gathered}$

$\underline{\sf{ Total\:surface\:area\:of\:cuboid\:is\: \textsf{\textbf{4,750 cm²}}.}}$
