Question

A cuboid has length$15feet$, breadth $12feet$, and height $10feet$. Find the total surface area of the cuboid.

Answer 1

Given, Length of cuboid $=15feet$

Breadth$=12feet$

Height $=10feet$

Total surface area of the cuboid

$\begin{array}{rcl}& =& 2\left[\right(length\times breadth)+(breadth\times height)+(height\times length\left)\right]\\ & =& 2(15\times 12+12\times 10+10\times 15)\\ & =& 2(180+120+150)\\ & =& 2\times 450\\ & =& 900squarefeet\end{array}$

Hence, the total surface area of the cuboid is$900squarefeet$.
